FIVE YEAR DRYDOCKING INTERVALS WITHOUT TIN?

The development in the 1970s of self-polishing antifouling coatings made intervals of five years possible between drydockings. These coatings are wholly dependent for their performance, however, upon tributyl organotin compounds that are chemically bonded to the polymer base. Concern over the effect of these compounds on the environment has caused governments to impose restrictions on their use. It is described how these regulations have sent coatings researchers back to the labs to find environment-friendly products with acceptable performance, but how an alternative comparable to tin-containing coatings has yet to be found. Thirty-six-month antifouling performance has been reached, but sixty-month systems are not yet realistic.
