摘要
The invention provides a cathodic electrocoat coating composition having (A) a polymer comprising at least one primary carbarnate group and at least one cationic salting site, (B) a curing agent having groups that are reactive with said fimetional groups on (A), and (C) a reactive additive comprising at least one compound having a 10 molecular weight of from 131 to 2000 and comprising at least one primary carbamate group and at least one alkyl group selected from the group consisting of branched alkyl groups of from 5 to 30 carbons, straight chain alkyl groups of more than 10 carbons, and mixtures thereof, wherein one or both of (A) and (B) comprise groups that are reactive with the primary carbamate group of (C).
