COATING COMPOSITION INCLUDING A UV-DEBLOCKABLE BASIC CATALYST

摘要

A coating composition is provided which is based upon (A) an activated unsaturated group-containing compound, (B) an activated CH group-containing compound and (C) a basic catalyst, wherein the basic catalyst is blocked with an acidic compound whereby the so-blocked catalyst becomes unblocked under the influence of UV light. These coating compositions possess extended potlife, good curing speed, and a good balance of physical and mechanical properties making them especially well-suited for a variety of coatings uses such as in paint, impregnating, sealing and bonding compositions.
