One-component high-elasticity waterproof coating formulation

Recipe introduction

This coating is used for waterproofing

Introduction of raw material ratio (parts by mass)

Preparation

(1) According to the above formula, stir the dispersant, film forming aid, defoamer, plasticizer, pH stabilizer, and ultraviolet light absorber in water for 20-30 minutes, and add pigments and fillers for high-speed dispersion for 30-40 minutes

(2) Pour the polyurethane/acrylate composite emulsion slowly, stir at low speed for 20-30 minutes, add leveling agent, defoamer, and thickener, and continue to stir at low speed for 10-20 minutes to obtain the formula

Raw material compatibility

The proportion of each component of the formula is in the range of 30~90 for polyurethane/acrylate composite emulsion, 5~45 for pigments and fillers, 0.

Among them, the polyurethane/acrylate composite emulsion is a self-made or commercially available waterborne polyurethane/acrylate building waterproof coating emulsion
