Abstract
The present invention provides a binder composition comprising a low molecular weight polycarboxylic acid, such as maleic anhydride, and a low molecular weight poly alcohol, such as polyvinyl alcohol, that exhibits improved cure performance with reduced emissions without sacrificing the performance of the final product or complication the manufacturing process. The binder composition may also incorporate a cure catalyst or accelerant such as sodium hypophosphite.
