Abstract
Electrodepositable coating compositions containing 1,1-di-activated vinyl compounds are described. The coating compositions produce cured coating layers that exhibit resistance to cratering. The coating compositions can be used in electrodepositable coating composition formulations.
Claims20
An electrodepositable coating composition comprising:
- (A) a polymer comprising (1) a reactive functional group and/or (2) a salt group or a salt-forming group;
- and
- (B) at least one component comprising:
- (b1) a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof;
- (b2) a polymerization reaction product of a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof;
- and/or
- (b3) an addition reaction product of (1) the polymer component (A) and (2) a 1,1-di-activated vinyl compound, or a multifunctional form thereof, or a combination thereof,
- wherein the 1,1-di-activated vinyl compound comprises a methylene dicarbonyl compound.
