Waterborne, ambient temperature curable film-forming compositions |
摘要 |
A homogeneous oil-in-water emulsion suitable for use as a curable film-forming composition is provided. The emulsion is a mixture of hydrophobic polyisocyanate crosslinking agent containing at least one tertiary isocyanate group and a surface active isocyanate reactive material. The surface active isocyanate reactive material comprises an active hydrogen-containing acrylic copolymer containing aromatic groups and having a glass transition temperature of at least about 0 DEG C. A multi-component composite coating composition is also provided by the present invention. The compositions are curable at ambient temperatures and are suitable for use in automotive applications.
