POLYURETHANE WATERPROOF COATING

POLYURETHANE WATERPROOF COATING

Two component polyurethane waterproof coating belongs to the category of two-component chemical reaction cured waterproof materials, in which component A is an isocyanate end capped material obtained by the condensation of polyether and isocyanate.The prepolymer of B component is a colored liquid composed of plasticizers, curing agents, thickeners, accelerators, and fillers. When in use, mix the two components A and B in proportion and apply them evenly on the surface of the waterproof base layer.
