Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
37 words
An inorganic binder composition comprising: (a) colloidal silica; (b) monoaluminum phosphate; (c) aluminum chlorohydrate; and (d) an amount of an alkyl tin halide catalyst effective to increase the bonding of said composition when applied to a substrate.
Claim 2
Dependent Claim
37 words
An inorganic binder composition comprising: (a) colloidal silica; (b) monoaluminum phosphate; (c) aluminum chlorohydrate; and (d) an amount of an alkyl tin halide catalyst effective to increase the bonding of said composition when applied to a substrate.
Claim 3
Dependent Claim
74 words
A composition according to claim 1 wherein the weight ratio of colloidal silica to monoaluminum phosphate plus aluminum chlorohydrate is about 0.6:1 to 1:1, the weight ratio of monoaluminum phosphate to aluminum chlorohydrate is about 0.8 to 1.0 to about 1.5 to 1.0 and the weight ratio of catalyst to the combined weight of the colloidal silica, the monoaluminum phosphate and the aluminum chlorohydrate is about 0.025 to 1.0 to about 0.125 to 1.0.
Claim 4
Dependent Claim
17 words
A binder composition according to claim 1 wherein the alkyl tin halide catalyst is triisobutyl tin chloride.
Claim 5
Dependent Claim
36 words
A binder composition comprising at least 10 wt. % of the composition of claim 1 and 90 wt. % or less of a dissimilar binder, said dissimilar binder being compatible with the composition of claim 1.
Claim 6
Dependent Claim
15 words
A heat resistant refractory coating comprising refractory materials and the inorganic composition of claim 1.
Claim 7
Dependent Claim
23 words
A refractory coating according to claim 5 wherein the refractory materials are alumina-silica fiber, carbon fiber, zirconia fiber, zirconium oxide or mixtures thereof.
