CURABLE COATING COMPOSITIONS CONTAINING BLENDS OF CARBAMATE-FUNCTIONAL COMPOUNDS

摘要

The present invention provides a curable coating composition that includes a t least three components. The coating composition includes a component (a) tha t includes one or both of a compound (a)(1) having at least one carbamate grou p or terminal urea group according to the invention and having at least two linking groups that are urethane or urea or a compound (a)(2) having at leas t two groups selected from carbamate groups, terminal urea groups, or combinations of the two and at least four urethane or urea linking groups. T he second component (b) of the coating composition includes an acrylic polymer comprising active hydrogen-containing functional groups reactive with the third component (c). Component (c) of the coating composition is a curing agent that is reactive with the first two components. Preparation of coated articles using the compositions of the invention is also disclosed.
