Jian Guo An Zhu No. 2 Two-Component Polyurethane Waterproof Coating
Component A is a polyurethane prepolymer obtained by the polycondensation reaction of polyether and isocyanate. Component B is a colored liquid composed of plasticizer, curing agent, thickener, accelerator, and filler. When used, components A and B are mixed in a certain proportion, stirred evenly, and then brushed onto the surface to be constructed. After several hours, the reaction solidifies into a waterproof coating that is elastic, tough, and durable.
