A thin-film intumescent composition for protecting a substrate against fire and thermal extremes includes a polymer binder, a solvent, a carbonific, a spumific, a catalyst, and at least some additives chosen from a source of carbon, finely divided elemental boron, a metal stearate adduct with alumina, and a conjugated fatty acid, preferably a conjugated triglyceride. The compositions provide chars having greatly increased efficiency, greater thickness, better physical characteristics including cell structure and physical toughness, and greater resistance to oxidation by fires and by chemicals present in fires.

A glass fiber capable of withstanding temperatures in excess of 1900. degree. F. is produced by treating a glass, preferably E-glass, fiber. The glass fiber is first leached with selected acids, and then the leached fiber is treated with organo-metallic materials of low viscosity, such as a dispersion of low molecular weight water-in-oil emulsion of dimethyl polysiloxane. The fiber is used in such applications as embedding it in a fire-resistant active coating material or embedding it into one surface of a polyolefin or composite plastic, such as a polypropylene sheet. The treated fiberglass can be used as a sole component or in concert with a fire-resistant or fire retardant material to further enhance its fire-resistant properties.
