Claims
- 1. A coating composition for inhibiting the development of barnacles on substrates exposed to a marine environment, said composition comprising 1) a carrier which in turn comprises rosin and a film-forming vinyl polymer, 2) at least one pigment, 3) at least one organic liquid for dissolving and dispersing the solid components of said composition, and 4) an effective amount of toxicant composition consisting essentially of between 10 and 15%, based on the total weight of said composition, of tri-n-butyltin fluoride, between 5 and 10% by weight of zinc oxide and between 3 and 10% by weight of a triazine ##STR3##selected from the group consisting of 2-ethylamino-4-isopropylamino-6-methylthio-s-triazine and 2-chloro-4-ethylamino-6-isopropylamino-s-triazine.
- 2. A coating composition as described in claim 1 wherein the film-forming vinyl polymer is a copolymer of vinyl chloride with other suitable ethylenically unsaturated materials.
