Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
87 words
A sealant composition for treating concrete surfaces consisting essentially of the following components: 25 to 40 parts epoxy resin, 10 to 20 parts of organic polysulfide elastomer which is compatible with the epoxy resin, 40 to 50 parts ethylene glycol monoethyl ether acetate, 15 to 25 parts ethylene glycol monobutyl ether, 30 to 45 parts of methyl ethyl ketone, the remainder of the composition comprising additional solvent diluents, and wherein the composition has a viscosity of 9 to 24 seconds measured with a Number 4 Ford Cup.
Claim 2
Dependent Claim
87 words
A sealant composition for treating concrete surfaces consisting essentially of the following components: 25 to 40 parts epoxy resin, 10 to 20 parts of organic polysulfide elastomer which is compatible with the epoxy resin, 40 to 50 parts ethylene glycol monoethyl ether acetate, 15 to 25 parts ethylene glycol monobutyl ether, 30 to 45 parts of methyl ethyl ketone, the remainder of the composition comprising additional solvent diluents, and wherein the composition has a viscosity of 9 to 24 seconds measured with a Number 4 Ford Cup.
Claim 3
Dependent Claim
58 words
A sealant composition for treating concrete surfaces as in claim 1 wherein the approximate content of the components set out therein is 35 parts epoxy resin, 15 parts organic polysulfide elastomer, 47 parts ethylene glycol monoethyl ether acetate, 20 parts ethylene glycol mono-butyl ether, and 40 parts methyl ethyl ketone with the remainder comprising said additional solvent diluents.
Claim 4
Dependent Claim
31 words
A sealant composition for treating concrete surfaces as in claim 1 wherein the solvent diluents approximate 70 to 80% by weight of the sealant composition, with solids comprising 20 to 30%.
Claim 5
Dependent Claim
22 words
A sealant composition for treating concrete surfaces as in claim 1 wherein a hardener is included for curing the epoxy resinous composition.
Claim 6
Dependent Claim
23 words
A sealant composition for treating concrete surfaces as in claim 4 wherein the hardener is heat cured at a temperature above room temperature.
Claim 7
Dependent Claim
16 words

Claim 9
Independent Claim
109 words
A method of treating a concrete surface which comprises applying to the surface a sealant solution consisting essentially of 25 to 40 parts of an epoxy resin, 10 to 20 parts of an organic polysulfide elastomer which is compatible with the epoxy resin, 40 to 50 parts of ethylene glycol monoethyl ether acetate, 15 to 25 parts of ethylene glycol monobutyl ether, and 30 to 45 parts of methyl ethyl ketone diluent, and the remainder comprising additional solvents, the parts being by weight and the solution having a viscosity of 9 to 24 seconds measured with a Number 4 Ford Cup, and heat curing the sealant following its application.
Claim 10
Independent Claim
109 words
