Abstract
Fabric base compositions having a refractory coating on one side and a coating of resin effective as a vapor and moisture barrier on the other side exhibit superior flame and heat resistance and superior dielectric properties in high moisture environments.
Claims15
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, said refractory materials being capable of fusing with the base fabric at elevated temperatures;
- and
- (c) a vapor barrier coating formed on the other side of said fabric wherein said vapor barrier coating is urethane resin, acrylic resin, epoxy resin, silicone resin, polyimide resin, polyamideimide resin, or polyester resin.
