BNBM PUM Two-component Polyurethane Waterproof Coating

Product Description:

The two-component polyurethane waterproof coating is a film formed by reaction and solidification of two omponents A and B. Component A is a transparent to light yellow viscous liquid containing isocyanate end group generated by polymerization of polyether, polyisocyanate and other raw materials; Component B is a paste formed by mixing and processing of cross-linking agent, accelerator, toughener, tackifier, mould inhibitor, filler and pigment. When in use, A and B components are mixed in a certain proportion, stirred evenly, scraped and coated on the base surface, and after several hours of reaction curing, a waterproof coating with elasticity, toughness and durability is formed.
