Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A heat resistant refractory coated fabric composition comprising: (a) a base fabric, and (b) a refractory coating comprising refractory materials and the inorganic binder composition comprising: colloidal silica; monoaluminum phosphate; aluminum chlorohydrate; and an amount of an alkyl tin halide catalyst effective to increase the bonding of said composition when applied to a substrate, said refractory coating bonded to the surfaces of the fabric, and said refractory materials being capable of providing flame abrasion resistance and heat resistance to the base fabric at elevated temperatures.
Claim 2
Dependent Claim
85 words
A heat resistant refractory coated fabric composition comprising: (a) a base fabric, and (b) a refractory coating comprising refractory materials and the inorganic binder composition comprising: colloidal silica; monoaluminum phosphate; aluminum chlorohydrate; and an amount of an alkyl tin halide catalyst effective to increase the bonding of said composition when applied to a substrate, said refractory coating bonded to the surfaces of the fabric, and said refractory materials being capable of providing flame abrasion resistance and heat resistance to the base fabric at elevated temperatures.
