ABSTRACT:
A binder composition for fibrous mats, preferably inorganic fibrous mats, which is fire resistant when cured is provided. The binder composition comprises a stable mixture of an aqueous aldehyde condensation polymer-based resin, a fire retardant latex and, optionally, an effective amount of an aqueous silica colloid, wherein the weight ratio of the latex to the resin is at least 1:1 on a non-volatile weight basis. The effective amount of the silica colloid is an amount sufficient to enhance the flame resistant property of the binder composition after curing and yet remain compatible with the components of the binder composition prior to curing.
