Abstract
An environmentally friendly, formaldehyde-free, aqueous binder composition that includes a carbohydrate, a crosslinking agent, and a pre-reacted product of an alcohol or polyol and monomeric or polymeric polycarboxylic acid or polyglycerol is provided. The pre-reacted product may include glycerol and esters of citric acid such a monoglyceryl citrate, diglyceryl citrate, and triglyceryl citrate as well as other higher molecular weight citric acid-based esters. The inclusion of the pre-reacted product in the binder composition helps to speed the crosslinking reaction, induces faster water evaporation, decreases the viscosity of the binder, helps to reduce the amount of water needed for application of the binder, decreases tackiness, and helps to achieve a maximum vertical expansion of the insulation pack in the transfer zone. The binder composition may be used in the formation of insulation materials and non-woven chopped strand mats.
