Polyurethane waterproof coating A STD-939
Introduction
The polyurethane prepolymer has a high resin content with excellent ratio of NCO, which can form a highly dense and elastic waterproof membrane after being cured and shaped by the curing agent.Our company’s several types of polyurethane prepolymer, with our corresponding curing agent, can reach different levels of waterproof membrane.The mixture is easy to apply, and can be applied by roller application or spray application according to the requriement of the project.
After mixing the polyurethane prepolymer with its corresponding curing component in the recommended ratio and ensuring thorough stirring,apply it using roller coating or spray coating methods.
Product Features
Scientific configuration: High resin content with scientific ratio of NCO, ensuring excellent performance and durability.
High density and elasticity: The forming waterproof membrane that is highly dense and elastic, providing superior protection against water infiltration.
Easy application: The mixture of the polyurethane prepolymer and curing agent is supporting roller or spray application methods for convenient application on different surfaces.
Durable and reliable: The waterproof film formed by the polyurethane prepolymer is durable and reliable, providing long-lasting protection against water damage and leakage.
