Abstract
Described herein are two-component curable compositions for coatings, paints, primers, topcoats, and the like. The systems herein include curable components that permit a wide latitude in additional additives used in the product formulation. In one aspect, the curable components of the compositions include a first component of polymer(s) or oligomer(s) having a beta-dicarbonyl group or dicarbonyl functionality of 1 or greater combined with a separate, second component of polymer(s) or oligomer(s) having an alkylidene malonate functionality of 1 or greater in the presence of a catalyst or initiator and other acidic compositional components.
Claims19
A curable composition comprising:
- (i) a first cure component of a polymer or oligomer having a dicarbonyl functionality of 1 or greater provided by a moiety on the polymer or oligomer having the structure of Formula (I)
- wherein
- X is a heteroatom linker or organic group to a polymer or oligomer backbone;
- Y is —OR1 or a —C1 to —C4 hydrocarbyl group;
- and
- R1 is a C1 to C20 hydrocarbyl group;
- (ii) a second cure component of another polymer or oligomer having an alkylidene malonate functionality of 1 or greater provided by the structure of Formula (III)
- wherein R6 is hydrogen, a C1 to C9 alkyl group, or an aryl group;
- and
- a catalyst or initiator;
- about 5 to about 15 weight percent of an acid;
- and
- wherein the curable composition includes additives having a pKa of about 7 or less.
