NEW DEVELOPMENTS IN ANTIFOULING: A REVIEW OF THE PRESENT STATE OF THE ART

This is a reprint of a paper that appeared in the Sept. 1978 Preprint Booklet of the American Chemical Society's Organic Coatings & Plastics Chemistry Division. The Authors, of Sigma Coatings B.V., first discuss some of the antifouling formulations that have been produced or proposed for overcoming the disadvantage of excess leaching of toxin in early life. The more recent developments towards the solution of this problem, and towards the improvement of anti-fouling compositions in general, are then reviewed under the headings:--Biologically-Active Organometallic Polymers and Copolymers; Effect of Composition of Copolymer on Hydrolysis and Film Erosion; Copolymerisation Mechanisms and Viscosity Control during Manufacture and Storage; Biologically-Active Copolymers of Maleic Anhydride and Methylvinylether. It is concluded that, probably, a practical limit has been reached in the efficacy of anti-fouling paints consisting of toxins dispersed in soluble or insoluble binders; only limited improvements will be achieved by using multiple coat layers. The development of tributyltin-modified copolymers, with their exploitation in practical anti-fouling compositions, has opened up a promising course of development towards extended service other organometallic toxins and metal-free organic toxins. It seems very probable that mixed biocides will often be required; it would be unwise to assume that tributyltin oxide is the most effective biocide. Some further conclusions are drawn, and the inadequacy of existing test methods is mentioned.
