Abstract
A glass fiber wool binder composition comprising a phenolic resole resin, animal bone glue, a sulfite process lignin and dicyandiamide is disclosed. When a binder composition of this invention is employed on glass fibers to produce uncured glass fiber wool, the uncured wool exhibits improved integrity, thus facilitating alignment of uncured wool in mold contours and the production of molded products.
