Abstract
A fibrous insulation product is discloses comprising a plurality of randomly oriented fibers and a thermoset aqueous binder composition at least partially coating said fibers. The binder composition 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 cross-linking agent comprising at least two carboxylic acid groups, and a short-chain polyol having at least two hydroxyl groups and a number average molecular weight less than 2,000 Daltons, wherein a ratio of long-chain polyol to short-chain polyol is from 0.1/0.9 to 0.9/0.1.
