Abstract
A curable formaldehyde-free binding composition for use with fiberglass is provided. Such curable composition comprises an addition product of an amine and a reactant to form an amino-amide intermediate. To the amino-amide is added an aldehyde or ketone to form the curable binder composition. The composition when applied to fiberglass is cured to form a water-insoluble binder which exhibits good adhesion to glass. In a preferred embodiment the composition when applied to fiberglass provides a sufficient blackness required in facer products.
