Single-Component Polyurethane Waterproof Coating

Product Overview

A moisture-curing reactive polymer coating formulated from isocyanates and polyethers. Manufactured through high-temperature dehydration and polymerization with hybrid curing agents and plasticizers. When applied, the prepolymer's -NCO groups react with atmospheric moisture to form a seamless, flexible rubberized membrane.
