The performance of high wear-resistant polyurea coating meets the national standard GB/T 23446-2009 Type II index, and is applied using specialized spraying equipment in China.The coating instantly solidifies, forming a high-strength, high elongation, and seamless elastic waterproof coating film.
Product Features
100% solid content, environmentally friendly new materials;
Rapid curing, reaching walking strength in 10 minutes, continuous spraying on the facade and top surface without sagging;
Low sensitivity to temperature and humidity reduces the risk of foaming in polyurethane waterproof coatings;
Spray continuously without seams, eliminating the risk of leakage;
The coating is dense, continuous, highly elastic, and has excellent waterproof performance;
High strength, high elongation, high tear strength, able to withstand erosion by water, seawater, acid, alkali, salt, etc;
Excellent crack tracking ability, able to withstand structural deformation without damage to the polyurea coating itself.
