Abstract
Fabric base compositions having a refractory coating on one side and a coating containing finely divided dielectric on the other side exhibit superior flame and heat resistance and superior dielectric properties.
Claims22
A heat resistant, flexible refractory insulating composition comprising:
- (a) a base fabric,
- (b) a refractory coating comprising refractory materials, said refractory coating formed on one side of said fabric and said refractory materials being capable of fusing with the base fabric at elevated temperatures;
- and
- (c) a dielectric coating comprising a finely divided dielectric which is mica, zirconium oxide or aluminum oxide, the zirconium oxide and aluminum oxide additionally containing a titanate of bismuth, calcium, magnesium, strontium, lead, zinc-magnesium or mixtures thereof, said dielectric coating formed on the other side of said fabric.
