ANTIFOULING SHIP BOTTOM PAINT WHICH CAN REDUCE FRICTIONAL RESISTANCE IN WATER

摘要

PURPOSE:To provide a consumable antifouling ship bottom paint which contains limited amounts of an antifouling agent and a pigment, gives excellent protection against contaminating organisms and reduces frictional resistance to sea water. CONSTITUTION:The antifouling paint is prepd. by adding a plasticizer, a solvent, an antifouling agent (e.g. copper suboxide) and a pigment (e.g. red oxide or clay) to a vehicle consisting of an acrylic polymer which contains about 65wt% or higher triorganotin salt of an alpha,beta-unsatd. mono- (or di-) basic acid (e.g. tributyltin methacrylate). The antifouling agent and pigment are added in such amts. that they may be contained in coating film in 20vol% or lower in total.
