Abstract
An aqueous binder composition is disclosed that comprises at least one long-chain polyol having at least two hydroxyl groups and a number average molecular weight of at least 2,000 Daltons; a primary cross-linking agent comprising at least two carboxylic acid groups; and a secondary cross-linking agent comprising a short-chain polyol having at least two hydroxyl groups and a number average molecular weight less than 2,000 Daltons.
Claims25
An aqueous binder composition comprising:
- at least 65 wt. % of a polymeric cross-linking agent comprising at least two carboxylic acid groups, based on the total solids content of the aqueous binder composition;
- at least one long-chain polyol having at least two hydroxyl groups and a number average molecular weight of at least 2,000 Daltons;
- and
- optionally, at least one short-chain polyol having at least two hydroxyl groups and a number average molecular weight of less than 2,000 Daltons;
- wherein a ratio of molar equivalents of carboxylic acid groups, anhydride groups, or salts thereof to molar equivalents of hydroxyl groups is from 1/0.75 to 1/5;
- and
- wherein the binder composition, once cured, includes no greater than 6.0 wt. % water soluble material.
