Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
41 words
A fluid resinous composition comprising a 1,2-epoxy resin formed by condensing epichlorohydrin with a compound containing active hydrogen and as a viscosity control agent therefor, 1.0 percent to about 25 percent based on the weight of the resin of glycidyl acetate.
Claim 2
Dependent Claim
41 words
A fluid resinous composition comprising a 1,2-epoxy resin formed by condensing epichlorohydrin with a compound containing active hydrogen and as a viscosity control agent therefor, 1.0 percent to about 25 percent based on the weight of the resin of glycidyl acetate.
Claim 3
Dependent Claim
17 words
A composition according to claim 1 wherein the 1,2-epoxy resin is the diglycidyl ether of bisphenol A.
Claim 4
Dependent Claim
28 words
A composition according to claim 1 wherein the 1,2-epoxy resin has an epoxy equivalent weight of 185-196 and a viscosity in centipoises at 25* C. of from 1,200-1600.
