WEB: std-coatings.com
Product Description
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.
Usage
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.
