Abstract

1408565 Anti-fouling paints CAMREX (HOLDINGS) Ltd 7 Sept 1972 [16 Sept 1971] 43260/71 Heading C3P [Also in Division C4] An antifouling composition for painting surfaces subject to marine immersion comprises a solids portion which includes a ground copper ore part of which is cuprous oxide, and a synthetic resin dispersing medium. The copper ore, which may have a natural content of cuprous oxide or may be roasted under reducing conditions to convert part of its copper content to cuprous oxide, is ground, e.g. to 300 mesh (B.S.S.) or a finer state, and is then incorporated into the dispersing medium. Additional cuprous oxide may be added to the ground copper ore, e.g. from 1 to 80 parts by wt. additional oxide per 100 parts total composition. Ore containing cuprous oxide is cuprite and ore requiring roasting is tenorite or melaconite, malachite, azurite or chessylite, chalcocite or copper glance, covellite or indigo copper, copper pyrites or chalcopyrite, erubescite or bornite, brochantite, atacamite, or sulphides of copper and iron. The dispersing medium may consist of or include chlorinated rubber or chlorinated compounds containing polyisoprene, vinyl or acrylic polymers, e.g. polyvinyl chloride, synthetic rubbers, e.g. polybutadiene and polybutylene, phenolic and epoxy resins, polystyrene, polythene and polypropylene. Conventional extenders and pigments may be included in the composition together with supplementary toxic ingredients, e.g. compounds of copper, mercury, lead, tin, phosphorus, arsenic, fluorine, or mixtures thereof, or organic insocticidal compounds.
