Abstract : A study is made to determine which commercial epoxies can be used as strength- transfer agents in the sea. In the first phase of the program, an attempt is made to determine the strength of the bond between the wire surface and the epoxy. However, due to the large data scatter, only approximations are possible. The second phase involves immersion of compression specimens in artificial seawater. Most of the epoxies show a loss in compressive strength of from 5 to 15 percent after a ninety-day time period. A few epoxies seem to be unaffected. Difficulty in keeping the salts from settling out of solution and lack of biological aspects lead to phase three. This last immersion test series lasts six months. Of nine different epoxies, three appear unaffected, two are slightly damaged, two are deemed unusable, and two are completely destroyed. (Author-PL)
