Abstract
A shelf-stable fast-cure aqueous coating is disclosed. The coating contains an anionically stabilized latex, a polyfunctional amine and a volatile base in an amount sufficient to deprotonate the conjugate acid of the amine.
Claims27
A shelf-stable fast-cure aqueous coating composition consisting essentially of:
- (a) an anionically stabilized emulsion polymer having a Tg greater than about 0.degree. C.;
