Over 100 organometallic polyacrylates, polyvinyls, polyesters, epoxies, and polyurethanes have been synthesized and are undergoing antifouling performance evaluation in Pearl Harbor, Hawaii, and Miami Beach, Florida. During accelerated aging trials, using a rotating cylinder apparatus, organometallic polymers have demonstrated from 1/2 to 1/15 the leaching rate of a Navy experimental antifouling coating, formula 1020A. The same organometallic polymers continue to exhibit 100% antifouling effectiveness after up to a 2 1/2-year ...
Development of novel, low-pollution-risk, antifouling organometallic polymers represents an advance in the state-of-the-art antifouling technology and promises to reduce the pollution from antifouling coatings at least tenfold. To date, acrylic, vinyl, styrene, and polyester organometallic polymers have shown excellent resistance to fouling organisms for 19, 17, 9, and 6 months, respectively, during panel immersion at Pearl Harbor Naval Shipyard. During accelerated aging trials, using a rotating cylinder apparatus, organometallic polymers ...
The report briefly evaluates the use of adhesives for estomers in marine environments. The following conclusions were found to be valid: The environment during application can be just as damaging to the performance of an adhesive joint during service as the service environment itself; practical adhesive systems for bonding elastomeric compounds under shipyard conditions for marine utilization must be specifically designed for tolerance to the application environment as well as ...
