NON-TOXIC ALTERNATIVES TO ANTIFOULING COATINGS

Fluorinated polyurethane coatings possess hard, smooth surfaces that resist the attachment of fouling organisms. These coatings derive their effectiveness from the low energy of their surfaces and not from the use of toxic ingredients. Following laboratory and field tests, these coatings were applied to U.S. Naval vessels on an experimental basis. Over a period of eight years, the coating on one boat remained intact, proved resistant to fouling and prevented corrosion of the hull. Non-toxic silicone elastomeric coatings are in the early stages of field testing. These coatings demonstrate superior resistance to the attachment of fouling, but some of them suffer from poor adhesion to the substrate and low mechanical strength.
