Aromatic Waterborne Polyester Polyurethane Dispersion
Brief introduction:
WPU-065 is waterborne polyurethane dispersion with functions of self-cross linking and fast drying at room temperature. It was synthesized with water as dispersion medium, adopted advanced formula design ideas and production process. Water-based coating film formulated by this resin has excellent performances such as high fullness, good flexibility and elasticity, good gloss, and abrasion resistance, non-toxic as well as harmless to human body.
