Abstract
Abstract Radiation curable compounds are disclosed which are derived from the reaction of siloxy-containing carbinol, a polyisocyanate and a polyfunctional compound having hydroxy and acrylic functional groups. The compounds have high cure rates, are compatible with other components of radiation curable, film forming compositions and impart good slip and other properties to cured film coatings.
