Publication number: 20230348682Abstract: Aqueous binder compositions having improved performance are provided. The aqueous binder compositions include 15 to 70 wt.% of a polymeric polycarboxylic acid, an amount up to 30 wt.% of a monomeric polycarboxylic acid, and from 5 to 55 wt.% of a monomeric polyol having at least three hydroxyl groups, wherein each wt.% is based on the total solids content of the aqueous binder composition. With respect to the polymeric polycarboxylic acid, the monomeric polycarboxylic acid, and the monomeric polyol, the ratio of molar equivalents of hydroxyl groups to carboxylic acid groups is from 0.5:1 to 2.5:1.
