Abstract
Abstract An adhesive epoxy resin composition particularly useful in underwater envnments which is the result of the admixture of a 3,4-epoxycyclohexylalkyl 3,4-epoxycyclohexanecarboxylate, exo-exo bis(2,3-epoxycyclopentyl) ether, endo-exo bis(2,3-epoxycyclopentyl) ether, a trialkoxyboroxine curing agent and a surfactant and methods of making said adhesive.
