ABSTRACT:
A non-woven fiber mat for use as a backing material for various components used in the building industry, and having improved fire resistant qualities. The mat comprises a blend of mineral fibers and glass fibers bonded together with a fire resistant binder system. The binder system comprises a mixture of a fire resistant latex and an aqueous aldehyde condensation polymer-based thermosetting resin. The preferred weight ratio of the latex to the aldehyde condensation polymer is at least 1:1 on a non-volatile basis. The binder may optionally further contain an aqueous silica colloid.
