Two-Component Polyurethane Waterproof Coating

Product Overview

A chemically reactive curing system consisting of:

Component A: Isocyanate-terminated prepolymer (polyether-isocyanate polycondensate)

Component B: Catalyzed compound blend (plasticizers, curing agents, thickeners, accelerators, and mineral fillers)

Curing Mechanism:
When mixed at specified ratios, the components undergo ambient-temperature crosslinking to form a seamless elastomeric membrane with rubber-like elasticity and superior waterproofing properties.
