Zusammenfassung: | 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.
La presente invencion proporciona una composicion aglutinante que comprende un acido policarboxilico de bajo peso molecular, como anhidrido maleico y un polialcohol de bajo peso molecular, como alcohol polivinilico que exhibe un desempeno del curado mejorado con emision reducida sin sacrificar el desempeno del producto final o complicar el proceso de elaboracion. La composicion aglutinante tambien puede incorporar un catalizador o acelerador del curado como el hipofosfito de sodio. |
