Coating Or Impregnation Provides Heat Or Fire Protection Patents (Class 442/136)
  • Patent number: 5658674
    Abstract: CVE polyorganosiloxane compositions crosslinkable into silicone elastomeric state, well suited for the protective coating of a wide variety of substrates and supports, notably vehicular airbags, are improvedly adhered thereto by including in said CVE silicone compositions an adhesiveness promoter comprising (1) at least one alkoxylated organosilane containing, per molecule, at least one C.sub.2 -C.sub.6 alkenyl radical, (2) at least one organosilicon compound containing at least one epoxy radical, and (3) at least one chelate of metal M and/or a metal alkoxide having the formula: M(OJ).sub.n, wherein n is the valency of M, J is a linear or branched C.sub.1 -C.sub.8 alkyl radical, and M is selected from among Ti, Zr, Ge, Li, Mn, Fe, Al and Mg.

  • Patent number: 5622774
    Abstract: Coating compositions for blocking heat from hyperthermal sources are reinforced with high-temperature, high emissivity, open weave fabrics. The coating compositions contain materials which actively respond to excessively high temperatures by undergoing endothermic processes or by swelling, preferably by both. The preferred fabrics are made of graphite or cardo-polymer yarns. The reinforced compositions may be applied directly to a substrate, or they may be molded into self-supporting shapes which are applied to the substrate or are themselves structural units.

  • Patent number: 5607758
    Abstract: Smoke containment curtains formed of flexible, smoke impermeable fabric formed of a fiberglass fabric substrate coated with a smoke impervious composition on at least one side. The coating includes a halide-free fire retardant incorporated into a halide-free acrylic or silicone resin. The resulting fabric has an LC.sub.50 of greater than 50 grams.

  • Patent number: 5604024
    Abstract: Products of reaction of an aluminum compound (A), a boron-containing acid (B), a phosphorus-containing acid (P) and an amine (N) are characterized in that 1 mol of (A) has been reacted with from 0.3 to 1.19 mol of B, (from 1.8 to 2.19)+x mol of P and (from 0.3 to 3.69)+y mol of N, where x=from -1.5 to +1.5 and y=from 0 to 12. These reaction products may contain, if desired, up to 30 mol of water per mole of A employed and may be used in a very wide variety of ways, for example as binders, coating compositions or insulating material.
