WATERBONE SELF-CROSSLINKABLE POLYURETHANE DISPERSIONS AND POLYURETHANE: ACRYLIC HYBRID DISPERSIONS

摘要

The present invention concerns a hybrid polymer dispersion comprising a functionalized polyurethane polymer (A) and a functionalised vinyl polymer (B) either as individual particles or as composites particles wherein the polyurethane polymer is prepared in a high boiling point oxygenated coalescing solvent having no functional group reactive with isocyanates and that will remain after water dispersion.
