High quality waterproof coating for walls, One-component polyurethane waterproof coating
Single-Component Polyurethane Waterproof Coating is made out of the main materials of isocyanate and polyether polyol, togethering with various auxiliaries and filled by polyreaction , coating on the waterproof base layer, after chemical reaction of NCO terminal group of polyurethane prepolymer and moisture in air.It forms a seamless elastomeric rubber waterproof membrane.
Main Feature:
1.Construction on the surface of the base in wet or dry a variety of materials
2. The coating has high strength tenacity, water resistance, weatherability, excellent durability
3. Can add pigment, forming a color coating
4. Non-toxic, tasteless, no pollution, construction safety supervision, short construction period
5. Construction at the top of the elevation, slope and top surface does not flow
6. With the base and cement mortar and other materials solid paste
7. High temperature resistance can reach 40 degrees
