Abstract
An inorganic composition prepared from colloidal silica, monoaluminum phosphate and aluminum chlorohydrate is employed as a bonding agent to bond refractory materials to a porous base fabric, such as fiberglass, to prepare fabric compositions that are flame and heat resistant and possess dielectric properties.
Claims14
A heat resistant, flexible, refractory, insulating composition comprising:
- (a) a porous base fabric;
- (b) a refractory coating comprising refractory materials and a bonding agent, said refractory coating formed on the surface and interstices of said fabric and said refractory materials being capable of fusing with the porous base fabric at elevated temperatures;
- and
- (c) a saturation coating formed on the outside surface of said refractory coating,
- said bonding agent and said saturation coating being an inorganic composition comprising colloidal silica, monoaluminum phosphate and aluminum chlorohydrate.
