Claims30
A coating composition comprised of at least one free radical-curable ethylenically unsaturated compound, at least one polyol and at least one polyisocyanate, wherein the at least one free radical-curable ethylenically unsaturated compound includes at least one isocyanurate tri(meth)acrylate or derivative thereof or at least one isocyanate functionality-containing urethane (meth)acrylate and the weight ratio of (polyol+polyisocyanate):
- free radical-curable ethylenically unsaturated compound is from 1:1 to 10:1.
A coating composition comprised of at least one free radical-curable ethylenically unsaturated compound, at least one polyol, at least one polyisocyanate, and at least one matting agent, wherein the at least one free radical-curable ethylenically unsaturated compound includes at least one isocyanurate tri(meth)acrylate or derivative thereof or at least one isocyanate functionality-containing urethane (meth)acrylate and the weight ratio of (polyol+polyisocyanate):
- free radical-curable ethylenically unsaturated compound is from 1:1 to 10:1, and wherein the coating composition is packaged in the form of two separate parts as follows:
- a-1) a Part A-1 comprised of at least one free radical-curable ethylenically unsaturated compound and at least one polyisocyanate;
- and
- b-1) a Part B-1 comprised of at least one polyol;
- or
- a-2) a Part A-2 comprised of at least one free radical-curable ethylenically unsaturated compound and at least one polyol;
- and
- b-2) a Part B-2 comprised of at least one polyisocyanate.
