ACRYLIC POLYURETHANE COATINGS INCLUDING POLYETHER POLYOLS

摘要

An acrylic polyurethane coating composition, comprising an isocyanate component comprising at least one polyisocyanate trimer; and an isocyanate reacting mixture, the isocyanate reacting mixture comprising from 25 wt % to 80 wt % of an acrylic polyol and from 1 wt % to 30 wt % of a polyether polyol, based on a total weight of the acrylic polyurethane coating composition, the acrylic polyol having a solids content of at least 50 wt %, based on a total weight of the acrylic polyol, and the polyether polyol having a viscosity of less than 500 mPa*s at 25° C. and a number average molecular weight greater than 300 and less than 700.
