B-STAGEABLE AQUEOUS BINDER COMPOSITIONS

Abstract:

An aqueous binder composition is disclosed that includes 5.0% by weight to 50.0% by weight of a monomeric polyol having at least four hydroxyl groups, based on the total solids content of the aqueous binder composition; and at least 50.0% by weight of a cross-linking agent comprising a polymeric polycarboxylic acid having at least two carboxylic acid groups, based on the total solids content of the aqueous binder composition. The aqueous binder composition includes a ratio of molar equivalents of carboxylic acid groups to hydroxyl groups is between 0.15/1.0 and 2.23/1 and has a pH of 2.2 to 4.0 and a viscosity at 40% solids and 25.degree. C. of 10 cP to 60 cP.
