Abstract
The heat and flame resistance of foamed plastics is increased by coating the foamed plastic with an inorganic binder composition of colloidal silica, monoaluminum phosphate and aluminum chlorohydrate. The inorganic binder compositions may optionally contain an alkyl tin halide catalyst, a water soluble organic resin, an elastomer or additional inorganic additives. The inorganic binder composition may be employed in combination with dissimilar binders.
