Claim Text:
1. An epoxy elastomer composition, comprising: a reaction product of a cycloaliphatic epoxide resin and an amine terminated polymeric polyol, the cycloaliphatic epoxide resin and the amine terminated polymeric polyol having a molar ratio in a range from 1:1 to 10:1; a catalyst that promotes the reaction of the cycloaliphatic epoxide resin and the aminated polyol to form an epoxy terminated prepolymer, where the catalyst is present in an amount from 0.1 wt. % to 5 wt. % based on the total weight of the cycloaliphatic epoxide resin, the amine terminated polymeric polyol and the catalyst; and an anhydride hardener, where the anhydride hardener reacts with the epoxy terminated prepolymer to form the epoxy elastomer composition.
