Abstract
An epoxy composition that includes an epoxy-terminated prepolymer, an alkanolamine hardener having at least one hydroxyl group and an organometallic compound, where amine groups of the alkanolamine hardener react with epoxy groups of the epoxy-terminated prepolymer in a stoichiometric ratio to form a cured epoxy composition. The epoxy-terminated prepolymer is formed from a reaction product of an amine terminated polymeric polyol and a molar excess of epoxy groups in an epoxy monomer, relative to a molar amount of amine groups in the amine terminated polymeric polyol.
