SOLVENT-FREE AQUEOUS POLYURETHANE DISPERSIONS AND METHODS OF PRODUCING SOLVENT-FREE AQUEOUS POLYURETHANE DISPERSIONS

摘要

A solvent-free aqueous curable polyurethane dispersion is derived from at least one isocyanate-terminated ethylenically unsaturated polyurethane pre-polymer in a reactive diluent. The polyurethane pre-polymer comprises at least one (meth)acrylate functional group and at least one isocyanate functional group. Methods for making a solvent-free aqueous polyurethane dispersion, curable compositions comprising the dispersion and resulting cured products are also disclosed.
