Abstract
A flame or heat flux protective coating composition, which includes a dispersion of fiberglass, hollow glass spheres, or a combination of both in silicone. A flame or heat flux protective sheet, which includes hollow glass spheres dispersed in silicone in a sheet form or fiberglass and silicone in a sheet form, wherein the fiberglass is dispersed in the silicone or the fiberglass is a woven cloth coated with the silicone is also presented. Articles incorporating the flame or heat flux protective coating or sheet form and methods for coating an article with the flame or heat flux protective coating composition are also presented.
Claims18
A sprayable flame or heat flux protective coating composition consisting of:
- (1) a silicone component comprising a polymer comprising dimethylsiloxane, wherein said silicone component starts to decompose at or above 400° F.;
- (2) fiberglass dispersed in the silicone component in an amount between about 8% and about 14% by weight of the composition;
- and
- (3) hollow glass spheres dispersed in the silicone component in an amount from about 0.1% to about 10% by weight of the composition.
A flame or heat flux protective sheet consisting of a woven cloth comprising fiberglass, wherein the cloth is coated with a sprayable flame or heat flux protective coating composition consisting of:
- (1) a silicone component comprising a polymer comprising dimethylsiloxane, wherein said silicone component starts to decompose at or above 400° F., and (2) hollow glass spheres dispersed in the silicone component in an amount from about 0.1% to about 10% by weight of the composition.
