Spraying Polyurea in Cold Weather: Tips and Considerations

Polyurea is a versatile and durable coating that offers excellent protection against corrosion, abrasion, and chemical exposure. It is commonly used in various industrial applications, including truck bed liners, waterproofing, tank linings, and concrete coatings.

When it comes to applying polyurea, temperature plays a crucial role in achieving a successful and long-lasting coating. Cold weather can present challenges, as it can affect the curing time, adhesion, and overall performance of the polyurea coating. In this blog post, we will discuss some important tips and considerations when spraying polyurea in cold weather.

Understanding the Impact of Cold Weather on Polyurea Coatings

Polyurea coatings are typically applied as a two-component system that reacts and cures quickly when mixed properly. The curing process occurs through a chemical reaction between the two components – the polymeric isocyanate and the amine-based curative. This reaction generates heat, which helps speed up the curing process.

In cold weather, the lower temperatures can significantly slow down the curing process, affecting the coating’s ultimate properties. This can lead to reduced adhesion, insufficient film thickness, and a compromised final finish. Additionally, the moisture content in the air can condense on the substrate, causing adhesion issues and surface defects.

Key Considerations for Spraying Polyurea in Cold Weather

  1. Substrate Preparation: Proper surface preparation is always critical when applying any coating, but it becomes even more important in cold weather conditions. Ensure that the substrate is clean, dry, and free from any contaminants that could compromise adhesion. If necessary, use a solvent-based cleaner or mechanical methods to remove dirt, oil, or rust.
  2. Temperature Control: To achieve optimal results, it’s important to maintain the recommended temperature ranges during the application process. Polyurea coatings generally have minimum and maximum temperature requirements, which may vary depending on the specific product. Make sure to check the manufacturer’s guidelines and follow them accordingly.
  3. Warm the Substrate: If possible, warm up the substrate before applying the polyurea coating. This can be done using a variety of methods, such as using space heaters, heat lamps, or infrared heaters. Keeping the substrate at the recommended temperature range helps to ensure proper adhesion and curing.
  4. Adjust Mixing Ratios: In cold weather conditions, it may be necessary to adjust the mixing ratios of the polyurea components to compensate for slower curing times. Reducing the amount of curative in the mix can help slow down the reaction and allow for better flow and leveling. Consult the product technical data sheet for specific recommendations on adjusting the mixing ratios.
  5. Pre-Heating the Polyurea: Another technique to combat cold weather challenges is pre-heating the polyurea components before mixing. This can be accomplished by storing the materials in a warm area or using specialized heating equipment designed for polyurea applications. Pre-heating ensures that the components are at the optimum temperature for a more consistent and effective reaction.
  6. Use a Heated Spray System: To overcome the challenges of cold weather spraying, consider using a heated spray system. These systems are specifically designed to warm up the polyurea components during application, ensuring that they remain within the recommended temperature range. Heated hoses and spray guns help maintain a consistent viscosity and promote proper curing.
  7. Monitor Humidity Levels: Cold weather is often associated with high humidity levels, which can lead to moisture-related issues during the application. Excessive moisture in the air can cause the coating to bubble, pinhole, or even delaminate. Monitoring and controlling humidity levels using dehumidifiers or air-drying equipment is crucial for a successful polyurea application.
  8. Consider Overall Thickness: Cold weather can affect the rate of curing, and it may take longer for the polyurea coating to achieve full cure. Consequently, it is recommended to apply thinner coats and build up the desired thickness gradually, allowing sufficient time for each coat to cure properly. This prevents issues like incomplete curing and shrinkage.

Conclusion

Spraying polyurea in cold weather requires careful planning, preparation, and thoughtful execution. By considering the impact of temperature, surface preparation, and proper mixing and heating techniques, you can achieve successful results in challenging weather conditions. Always remember to consult the manufacturer’s guidelines and technical data sheets for specific recommendations on spraying polyurea in cold weather.

Are There Any Regulations To Know About Before Starting A Polyurea Business In Canada?

For entrepreneurs considering starting a polyurea business in Canada, there are a few regulations to consider before starting. From obtaining permits and licenses to understanding health and safety standards, it’s important to do your research and ensure you are up-to-date with the latest rules and regulations that apply in your province or territory.

Getting Started: Starting A Polyurea Coatings Business

The first step in setting up a polyurea business is to secure the necessary permits and licenses to begin operations legally. Depending on where you plan on conducting business activities will determine what type of permits you require; some may include building permits for operating out of a storefront or workspace or even environmental permits if you plan on disposing of hazardous materials associated with the production process or any chemicals that could put human health at risk. Depending on the services provided and the products sold, you may also need insurance coverage for your business. Understanding local laws regarding taxation may also be important when establishing your business, so look into this beforehand.

Health & Safety Standards

In terms of health and safety standards related to polyurea production activities, the Canadian Centre for Occupational Health & Safety (CCOHS) provides information about recommended workplace safe practices when handling hazardous materials found in polyurea products such as isocyanates – which can cause skin irritation upon contact – silicone polymers – which can cause burns if not properly handled – and other chemicals present in various formulations used during manufacturing processes. The CCOHS also outlines additional protective measures such as wearing personal protective equipment (PPE) like gloves and goggles while working with these chemicals, ensuring adequate ventilation systems are installed in workspaces where needed, and properly storing all hazardous materials away from areas frequently accessed by workers or consumers.

Local Regulations

It’s also essential for those looking to start a polyurea business in Canada to familiarize themselves with local regulations regarding environmental protection measures related to hazardous waste disposal and the usage of volatile organic compounds (VOCs). Depending on the specific product being used and where it is being applied, special handling protocols may need to be followed when disposing of any residues or byproducts generated during the application process. Furthermore, some provincial and territorial governments have imposed restrictions on VOC levels associated with certain products used for spray-on applications like polyurea coatings due to their potential impacts on air quality. Businesses operating within these jurisdictions must ensure they comply with all relevant legislation pertaining to emissions from these activities before starting operations.

Marketing Requirements

For those who wish to market their services related to polyurea products in Canada, there may also be several marketing requirements that need to be taken into consideration depending on which provinces/territories you plan on targeting your services. For instance, Quebec has very strict advertising laws which require businesses targeting consumers within its borders must abide by provincial language restrictions when designing any promotional materials used for communication purposes (e.g., website content etc.). Failure to do so can lead hefty fines if found guilty of breaking any rules set out by this province’s language laws governing advertising efforts made by companies operating within its jurisdiction(s).

Business Insurance

Finally, entrepreneurs should not forget about obtaining insurance coverage for their new venture prior to commencing operations; this will help protect them financially should anything unexpected happen during the course of running their business (e.g.; accidents/injuries sustained by workers or damage resulting from unforeseen events etc.). In addition, depending upon the particular services offered by one’s establishment an additional liability policy might also come into play given certain types of polyurea work can prove quite risky under certain circumstances; having such coverage could prove invaluable should something go wrong the line either within one’s own company or another party directly involved in one’s operations – even if indirectly!

Purchasing Polyurea Products

When it comes to purchasing supplies for your polyurea business, one company leads the pack and has been the go-to distributor for over 30 years. ArmorThane has revolutionized the polyurea industry the way Tesla revolutionized the car industry.

The Newest Frontier in Coatings

Polyurea has become highly utilized for various applications previously dominated by epoxy, acrylic, and polyurethane. Specifically, the aliphatic polyurea compounds frequently find themselves as the coating of choice due to their superior mechanical properties.

Capable of smoothly adhering to substrates like cement, brick, and fiberglass, polyureas are now used for scores of building applications such as encapsulating asbestos ceilings or coating floors. Unlike polyurethanes, polyureas cure under high moisture and humidity conditions, as long as the correct surface preparation is undertaken.

Within the manufacturing and process industries, polyureas are now used in everything from the lining of storage tanks to covering shop floors and plant walls. Polyureas vastly outperform paint, which often cannot hold up to rigorous cleaning procedures practiced in pharmaceutical and food processing plants, for example. The remarkably fast reaction time (3 to 7 seconds) of polyurea systems appeals to facility management as it permits quick installation with only minimal disruption to process operations.

These performance benefits explain, in part, why the booming demand for polyurea systems should continue well into the future. “From what we’ve learned as an association, in addition to my interactions with applicators in the field and companies that manufacture the systems and the raw materials, I see a 15 to 20 percent growth per year in this industry,” says Dudley Primeaux, former president of the Polyurea Development Association and owner of Primeaux Associates LLC of Austin, Texas. As the prime inventor of sprayed-polyurea systems, Primeaux is well-positioned to provide consulting advice to contractors interested in entering the field.

A Little Background Knowledge Goes a Long Way

Polyurea systems are formed from the combination of two components: isocyanate and an amine resin. These components’ union forms an extremely flexible urea linkage, unlike the crystalline nature of polyurethane systems. The initial formulations were introduced in 1986 when somebody told Primeaux, then a chemist with Texaco Chemical Co./Huntsman Chemical, that polyureas couldn’t be sprayed. The system worked the first time because the equipment delivered both the A and B components in a predictable, consistent manner. 

The first commercial sprayed-polyurea coating was delivered for a roofing system in 1989, and the history of coatings systems has been forever changed. But the polyureas provide optimum performance only when mixed correctly, and according to Primeaux, choosing the right equipment to handle this task is critical.

Image result for Polyurea Market

The Challenge of Getting the Right Mix

No chemical catalyst is required, but special plural equipment is required due to the extremely fast reactivity and cure. High pressure is necessary to force the components to mix. High temperatures are also needed to lower the viscosity to enhance the mix and atomization. Heating occurs at the pump and the hoses, while the actual mixing takes place inside the components meet at high velocity. This mechanical mixing is critical to uniform concentration (hence, better adherence. The importance of obtaining equipment specifically designed to spray polyureas cannot be over-stressed.

The quality and the tolerances in the manufacturing of the spraying equipment make a huge impact on the output of your product,” stresses Primeaux. “Good equipment costs more, but this is not the place to skimp when you want to spray polyurea. The key to processing is within the proportioning pump and the spray gun. This is the ‘life support’ system for proper installation and application.”

Image result for Polyurea Market

It All Begins at the Pump

When spraying with polyureas, special consideration starts with the selection of a high-output pump. Increased pressure delivers more kinetic energy to the mixing zone. Pumps can be either pneumatic or hydraulically operated. Both types still require an air compressor because the air drives the drum pumps that deliver the material. The choice in pumps is then divided into either a vertical or horizontal layout.

The vertical pump has been the traditional choice of paint contractors. However, with high-solids coating systems like polyureas, verticals will not fill components of different viscosity at the same time and rate of speed. An imbalance of pressure will always be noted between the up and downstroke. This often results in a pulsating flow of material to the spray gun and affects the spray pattern and the coating consistency.

Polyureas must be mixed with an even and strong head of pressure. If the pressure varies on one side or the other, the quality of the mixed material and the spray pattern’s consistency at the gun can be adversely affected. And without sufficient volume, poor mix, atomization, and application result.

Hoses

The hoses that carry the gun components must also be heated; otherwise, all the gains in breaking down the pump’s viscosity would be lost. Regular hoses, designed for polyurethanes, cannot handle the higher temperatures and pressures required for spraying polyureas. While the initial healing takes place within the pump, the hoses must maintain that temperature throughout their entire length — even as long as a football field. Such demands require specially designed hoses.

Primeaux added that, depending on the length, hoses should include a “step-down” inside diameter (ID) to minimize pressure drop at the spray gun. In other words, the ID at the pump end of the hoses is larger than the hose section near the gun.

The Spray Gun

Guns are divided into the categories, mechanical and air, depending on how the material is purged out of the chamber when detriggering occurs. Solvent purge guns are also occasionally utilized for hard-to-mix or off-ratio spray applications.

Representing the most applicable spray gun for the application of polyurea technology is the mechanical purge spray gun. With a machine gun, the valving rod’s return at detriggering seals off and completely flushes out the mixing chamber area. The tight fit of the valving rod, along with the high-pressure kinetic force of its movement, cleans all unwanted material out.

“The mechanical purge gun gives the best mix and properties, partly because of the dynamics within the mixing chamber,” says Primeaux. “You also get a complete purge out of the mixing chamber, which eliminates the possibility of the hold-up of product inside that chamber. The problem with hold-up is that it affects the incoming material and the subsequent mix.”

With air purge guns, a blast of air blows the material out upon detriggering between sprays. Here, the valving rod moves back and forth to allow air to enter the mixing chamber instead of just material.

The shortcoming of air purge guns is that since air is used to purge, the pressure must be consistently high to flush the chamber completely. If not, the tip will become plugged. An additional problem occurs whenever air enters the mixing chamber. Contaminants such as oil and water could be introduced from the air compressor onto the substrate. This can cause blistering and delamination of the polyurea coating.

Additional Gun Considerations

Other considerations when choosing a gun are gun geometry and construction. Maintenance and speed of operation also rank as important factors when selecting polyurea spray systems. Operator ergonomics should be taken into account as well. Finally, contractors new to the polyurea spraying industry should also seek an equipment manufacturer that provides good support and a commitment to maintaining a ready spare parts inventory.

Do the Job Right the First Time

Ultimately, contractors reap the benefits of knowing which equipment to use for entering the field of sprayed polyureas. On the other hand, the consequences of ignorance can put a contractor out of business.

When working in the trenches with these applicators, you can see the results of using poor equipment right up front. I know of one case where a guy did a job for a customer, but two things went wrong. The contractor didn’t do the right surface prep, and the equipment was not suitable for the field application of polyurea. When the coating failed, the customer sued the contractor several times for what the d was worth because of lost revenue.

SPRAY, COAT, AND CONTAIN

Traditional coatings have been too inflexible and not sufficiently elastic to accommodate ground, concrete, or metal substrate movement for primary or secondary containment. This deficiency can lead to cracks or holes forming in both the substrate and the coatings, which can compromise containment. However, the formulation of tough, monolithic, flexible coatings such as polyurea is now resolving this issue for contractors, engineers, and facility managers. When applied directly to concrete or metal surfaces, polyurea not only strengthens and protects lite underlying substrate but can also bridge gaps or cracks of 1/8″ or larger.

Image result for containmenmt polyurea


Furthermore, polyurea is now being applied to geotextile liners that can be swiftly rolled out in sheets to protect more heavily diminished surfaces or for use in field applications such as dirt or gravel pads at drilling sites. Once installed, applicators need only coat the liners’ seams to create a monolithic surface suitable for containment. Whether at refineries, industrial plants, or other manufacturing plants, regulations demand the use of primary and secondary containment systems to keep toxic or hazardous substances from escaping into the ground and potentially entering the water supply.

Image result for containmenmt polyurea

This implies primary containment is not foolproof. Though durable, metals corrode, concrete cracks, and is permeable, it will drain liquids if uncoated.
Therefore, secondary containment, in the form of concrete pits with barriers installed around the perimeter of a tank or other storage container, is often needed. To protect these structures, coatings such as epoxies, tars, and polyurethanes are often applied as an added protection wall. However, these traditional coatings are often inflexible when cured and can crack along with the concrete. Typical coatings do not hold up well to substrate movement or daily, seasonal, or process-related thermal expansion and contraction, which can lead to cracks and leaks.


After considerable research and testing, Collins says he turned to an advanced polyurea system from ArmorThane, a spray-applied polyurea manufacturer for primary and secondary containment. When applied to substrates such as concrete or steel, the spray-applied waterproof coating creates a durable, seamless, flexible, protective barrier that stops leaks and strengthens primary and secondary containment systems’ integrity. The coating exhibits superior physical properties such as hardness, tensile strength, and crack bridging and elongation up to 400% to create a robust, industrial-grade protective lining.

Polyurea can bridge cracks as well as flex at a rate similar to concrete and steel. This not only helps it last but also seals the concrete, so does Secondary containment, in the form of concrete pits tamers instated around the perimeter of a tank or other storage container, is often required as a back-up to primary containment does not absorb contaminants if there is a spill inside the contained area. While traditional coatings such as cementitious, epoxies, tars, and polyurethanes will prematurely fail if not installed under a relatively narrow range of temperatures, polyurea is designed for installation and use from ~4O°F to *35OCF. It sets and cures quickly and will withstand decades of freeze-thaw cycling and wide
After spraying the polyurea, return to service is almost instantaneous variations of temperature and humidity. After spraying the polyurea, return to service is almost instantaneous, making a big difference in minimizing production downtime.


They coated about 8,000 sq. ft. of concrete in 12 truck-offloading areas that required drive-in containment with ArmorThane polyurea. In some instances, trucks were safely driving across the concrete within minutes of spray application. Instead of spraying polyurea directly to the substrate, pre-sprayed composite panels can offer advantages for containment over soil, gravel, or even concrete that is too damaged to be effectively rehabilitated.

Repairing plastic liners also presents a problem at the seams, when damaged areas are cut out and new sections. Polyurea products are so much more durable than plastics for containment systems. When needed, they can custom apply more polyurea millage to geotextile panels and berms to accommodate even the heaviest truck use and vehicle abuse. To verify the strength of the polyurea coating on containment mats and berms, in fact, Collins conducted several tests.

They also ran 6,044 fully loaded water trucks across a containment system, and it withstood it with zero holes and no compromise to the liner. Collins credits both the durability of the ArmorThane polyurea and its extended recoating window for the ability of his company to reuse its containment systems extensively. To reuse a containment system, they cut it up into rolls, roll it up and move it. Then, take it back out, respond to certain areas, and reinstall the original containment system at another location. They’ve found the extended open window for recoat and repair of the polyurea allows them to cut out any damaged section of geotextile easily, put a new piece in, and spray the seams to make it virtually seamless again. They get better repair and more reuse out of our containment systems.

A Look At The Everchanging Industrial Protective Coating Market

Amine-cured epoxy is one of the most successful chemically resistant coatings on the market. They tend to come as epoxy with filler and other additives on the A-side and amine curative on the B side. When mixed, they give a sprayable coating with a very workable pot life and good adhesion to a wide variety of substrates. The cured epoxy coating’s ultimate chemical resistance will depend on several key factors, including the chemical composition of both the epoxy and the amine curative, the types of fillers and additives used, and the cure temperature and time. 

Crosslink density of traditional epoxy coating compared to polymer-modified epoxy coating.

With a low crosslink density, a coating is susceptible to penetration from corrosive chemicals, which can eventually reach the substrate, creating corrosion and leading to its ultimate failure. However, with a very high crosslink density, the product provides a virtually impenetrable barrier between the chemical and the substrate. Also, chemicals do not penetrate the coating, which can occur in common epoxies, leading to blistering, splitting, and coating degradation. 

Chemical penetration of coatings with different crosslink densities.

In a low-crosslink-density coating, the chemicals will penetrate through the coating to the substrate, causing substrate corrosion. Because the solvent has penetrated the coating, both the epoxy and amine curing agent bonds will be broken by chemical attack. As for the coating with high crosslink density, the chemicals will be unable to penetrate the coating. This will not only protect the substrate from corrosion but also protect the coating itself from any damage.

With the emerging needs for both industrial and marine applications, coatings have a wide range of technical requirements in addition to chemical resistance. We will cover the technical and market needs for each of these requirements along with recent developments to meet these demands.

Coatings for Sulfuric Acid

Sulfuric acid is a very important industrial chemical used for such things as the manufacturing of phosphate fertilizers, purification of petroleum, acids, along with being used as a pickling medium for metals, and in storage batteries. 

Two-component epoxy coatings show excellent resistance to sulfuric acid of most concentrations and transportation and storage temperatures. They have been used successfully for years, but unfortunately can darken upon exposure to sulfuric acid.

Coating Inspection Facilitation

Ensuring the integrity of the coating is critical for the protection of the substrate. Failure of the coating cannot only cause destruction to the vessel, costing the owner both time and money, but it can also pose a danger to workers and the surrounding environment. Proper inspection of the coating itself can be time-consuming and expensive, and based on the vessel’s geometry being examined, some areas can be very hard to probe. Coatings must regularly be examined for damage to make sure that there are no cracks, holes, or chips. The entire vessel must be examined after draining and cleaning, which can be difficult again because of the complex geometries along with the hazards associated with sending workers into the vessels for review.

Antistatic Coatings

Static electricity presents a very significant risk for not only the safety of people and property but also of products that are susceptible to static electricity, such as electronics components.

Improved Abrasion Resistance

Coatings used to stock chemicals and other substances can sustain damage from abrasion, such as the loading and unloading of supplies in the form of slurries or from cleaning procedures. Applications that could benefit from an improvement in abrasion resistance could include hopper cars, slurry pipes, legs of oil platforms, pumps, coal chutes, baghouses, and ion exchange vessels. Epoxy coatings can provide great chemical resistance through a high degree of crosslinking and the correct chemical structure, however this can lead to a coating that can be brittle and subject to damage from abrasion.

Field-Repairable Coatings

Recent changes to regulations from the American Association of Railroads (AAR) require that for a tank car facility to be certified, it must be able to demonstrate the procedure to repair coatings on a periodic basis. 9 High-bake phenolic coatings are widely used in the rail industry due to their excellent chemical resistance to a wide variety of products. Repair of high-bake phenolic coatings requires that the tank car first be returned to the facility, where the coating repair would then be demonstrated. The coating repair of high-bake phenolics requires that the entire tank car be taken up to high temperatures (350 °F to 400 °F), which can damage the exterior paint and stencils. This adds an extreme amount of cost for the tank car facility, along with a great deal of time for the tank cars to be out of service. Having a coating that can have its repair demonstrated in the field is therefore very important to tank car facilities. Two-part epoxy coatings can meet these needs.

Future Industry Needs

Vessel owners continue to look for ways to reduce operating expenses, and therefore chemical-resistant coatings must deliver opportunities to achieve these goals. One such opportunity is for coatings that release cargo from the walls faster than current technologies. This would allow for quicker unloading of vessels, along with easier cleaning, allowing for less time between unloading and loading. Ability to carry different chemicals would also save vessel owners time and money. The same asset could be used to transport or store a wide variety of chemicals, eliminating the need to either re-coat current vessels or to possess different storage options for each chemical. The coating should therefore be resistant to the widest variety of chemicals possible and should not absorb chemicals that can later be released and contaminate the next chemical loaded into the vessel. 

Conclusion

Developments in chemically resistant, 2K polymer-modified epoxy coatings have met several market needs, including carry of sulfuric acid, coating inspection facilitation, improved abrasion resistance, anti-static coatings, and field-repairable coatings. These coating systems continue to be rulers in chemical-resistant applications in both marine and industrial applications, and will meet anticipated market needs through continued innovation.
