Waterproof and corrosion protection:
Polyurea coatings have moisture insensitivity /resistance. They have low permeability and are also resilient to water, providing corrosion protection. Therefore, they are also used as tank linings.
Fast set and return to service
A curing time of seconds or minutes means there is an almost immediate return-to-service time, and downtime is many times less than with another paint.
100% Solids
With a 1:1 volume ratio, the need for extra coats is eliminated, and the lack of solvents means it also VOC free and environmentally friendly.
High resistance
A polyurea coating provides chemical, abrasion, and UV resistance, as well as being able to withstand extreme temperature changes.
Strength and flexibility
Polyurea has a high polymeric elongation meaning that it stretches as well as resists punctures and tears. A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which
Why would you choose polyurea coating instead of a more traditional coating like epoxy? While other coatings have their own benefits, polyurea outperforms them in certain areas.
POLYUREA VS POLYURETHANE
Though these coatings are related (both isocyanate-based), they have many differences. When being applied polyurethane based coatings are sensitive to temperature and moisture, where polyurea is not. Polyurea is elastic and can stretch, but polyurethane cannot. It also has a higher tensile strength
POLYUREA VS EPOXY
Epoxies are sensitive to temperature, humidity and moisture during application, with longer cure times than polyurea. Epoxy coatings are not flexible with the expansion of a substrate, and UV radiation will cause it to discolour, unlike polyurea.
Polyurea vs. Cementitious:
Unsurprisingly, cementitious coatings provide little give, and have far longer setting times than polyurea. All cementitious coatings have long setting and curing times.
