7 Essential Facts About Moisture-Cured PU Catalyst You Need to Know

1. What is Moisture-Cured PU Catalyst?

Moisture-cured PU (polyurethane) catalysts are essential components used in the curing process of polyurethane foams and coatings. These catalysts accelerate the reaction between polyols and isocyanates in the presence of moisture. This feature not only speeds up drying times but also enhances the durability and performance of finished products.
