Single-Component Water-Based Polyurethane Waterproof Coating
This product is a high-elasticity, eco-friendly waterproof coating made from a water-based polyurethane dispersion, combined with pigments, fillers, and additives. Using water as the dispersing medium, it forms a tough, seamless rubber waterproof layer through water evaporation and molecular self-crosslinking. It combines the excellent performance of solvent-based polyurethane with the environmental advantages of water-based products.
