COMBINED ORGANIC/INORGANIC POLYOLS IN WATERBORNE FILM-FORMING COMPOSITIONS |
摘要 |
A water dispersible polyurethane dispersion suitable for use as a curable film-forming composition is provided wherein the dispersion comprises, in water, the reaction product of (i) an acrylic polyol having hydrophilic groups, (ii) a polyol hydrosilylation reaction product of an alkylpolysiloxane and an unsaturated hydroxyalkyl compound, and (iii) a polyisocyanate component. Preferably, the acrylic polyol comprises a copolymer containing aromatic groups and having a glass transition temperature of at least about 0 DEG C. |
