MAN 0242 PUS 6767 ACIDIC GLASS FIBER BINDING COMPOSITION, METHOD OF USE AND CURABLE GLASS FIBER COMPOSITIONS Abstract Described is an acidic glass fiber binding composition comprising an aqueous soluble phenol formalde- hyde resin having low free formaldehyde, an effective amount of a formaldehyde scavenger, and an effective amount of a strong aqueous soluble acid, wherein the composition has an acidic pH and the solids content ranges from about 1 to about 30% by weight of the total composition. Also described is a method of binding glass fibers such as newly formed warm glass fibers at junctions of the fibers by applying the composition as described above to the fibers and then drying the composition. Also described are B- staged and C-staged glass fiber compositions having a alkylamine content less than 5 ppm. 18922_1
