USE OF BETA-HYDROXYALKYLAMIDE IN AMBIENT AND LOW BAKE LIQUID COATINGS

An aqueous coating composition comprising an active hydrogen-containing polymer, an isocyanate, and beta-hydroxyalkylamide is disclosed. The polymer can be any number of polymers containing hydroxyl, amine and/or thiol groups, such as an acrylic polyol, a polyester polyol, and mixtures thereof. The...

More Information
Summary:An aqueous coating composition comprising an active hydrogen-containing polymer, an isocyanate, and beta-hydroxyalkylamide is disclosed. The polymer can be any number of polymers containing hydroxyl, amine and/or thiol groups, such as an acrylic polyol, a polyester polyol, and mixtures thereof. The hydroxylalkylamide has been shown to decrease the time in which the coating achieves hardness and, in the case of the polyester polyol system, increases the hardness that is achieved. The present compositions also provide resistance to chemical exposure. Methods for coating a substrate and the substrates coated thereby are also disclosed.
