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.
Claims14
Radiation polymerizable compound comprising the reaction product of:
- (A) at least one siloxy-containing polycarbinol compound;
- (B) a polyisocyanate;
- and
- (C) a polyfunctional compound having at least one functional group which is reactive with an isocyanato group of said polyisocyanate and which polyfunctional compound after reaction with said isocyanato group provides at least one ethylenic functional group in said reaction product.
