Two-component Polyurethane Waterproof Coatings
Applicable Standards：GB/T 19250-2013
Product Introduction
Two-component polyurethane waterproofing coating is a type of two-component chemically reactive waterproofing coating, in which Component A is a prepolymer obtained through the polymerization of polyether polyol and isocyanate, and Component B consists of curing agent and additives. When in use, mix Component A and Component B evenly in the specified ratio; after application, the mixture cures through chemical reaction to form a rubber-like elastic coating film with a defined thickness, thereby achieving the waterproofing effect.
Product Features
1、It is free of harmful substances such as coal tar and coumarone, and has excellent rubber elasticity and resilience.
2、It has outstanding mechanical properties, with high strength and elongation at break, as well as strong adhesion to the substrate.
3、It exhibits excellent corrosion resistance, aging resistance and mold resistance.
4、It has superior low-temperature resistance and water resistance.
5、It is free of harmful solvents such as xylene, and is non-toxic, non-irritating in odor and environmentally friendly.
