Spinosyn antifouling compositions, methods of use thereof and articles protected from attachment of biofouling organisms

Abstract

Disclosed herein are antifouling compositions including at least one spinosyn active material. These compositions provide protection to surfaces coated or impregnated therewith from attachment of various biofouling organisms. Compositions include, for example, paint, varnish, and sealant formulations.

1 - 30 . (canceled) 
     
     
         31 . A marine or freshwater antifouling coating composition comprising at least one spinosyn or salt thereof and a carrier, wherein said composition is effective to inhibit adhesion by aquatic organisms, chosen from organisms belonging to the family Balanidae; bacteria belonging to the species  vibrio  sp.,  flavobacterium  sp.,  alcaligenes  sp. and  aeromonas  sp.; and diatoms; to articles to which said composition is applied. 
     
     
         32 . The marine or freshwater antifouling coating composition of  claim 31 , wherein said carrier is chosen from a film-forming agent, cementitious material, thermoplastic material, fiberglass, elastomeric material, and vulcanized rubber. 
     
     
         33 . The marine or freshwater antifouling coating composition of  claim 31 , wherein said composition is chosen from paints, varnishes, primers, and sealants. 
     
     
         34 . The marine or freshwater antifouling coating composition of  claim 31 , further comprising at least one additional active ingredient chosen from antifouling biocides, microbicides, natural origin antifoulants, antifouling metal salts, bactericides, fungicides, algaecides, insecticides and antibiotics, including free or encapsulated forms of the above or mixtures thereof. 
     
     
         35 . The marine or freshwater antifouling coating composition of  claim 34 , wherein the at least one additional antifouling biocide is an isothiazolone. 
     
     
         36 . The marine or freshwater antifouling coating composition of  claim 34 , wherein the at least one additional antifouling biocide is chosen from copper and/or zinc containing compounds including salts and derivatives thereof. 
     
     
         37 . The marine or freshwater antifouling coating composition of  claim 31 , wherein the at least one spinosyn is chosen from spinosad, spinetoram, and butenyl spinosyn. 
     
     
         38 . The marine or freshwater antifouling coating composition of  claim 31 , wherein the spinosyn is present in a percentage of 0.001% to 90% 
     
     
         39 . The marine or freshwater antifouling coating composition of  claim 31 , wherein the spinosyn is present in a percentage of 0.1% to 10%. 
     
     
         40 . The marine or freshwater antifouling coating composition of  claim 31 , further comprising at least one additive chosen from pigments, organic diluents, fillers, extenders, swelling agents, wetting agents, antifreezing agents, adhesion promoters, UV stabilizers, flatteners, preservatives, and combinations thereof. 
     
     
         41 . The marine or freshwater antifouling coating composition of  claim 31 , wherein the composition is a controlled release composition. 
     
     
         42 . A product comprising a submergeable marine or freshwater structure protected against fouling organisms wherein said protection is afforded by the coating composition according to  claim 31 . 
     
     
         43 . The product of  claim 42  wherein said protection is afforded by a coating composition having been applied on said structure, said coating composition comprising a film-forming polymer binder. 
     
     
         44 . The product of  claim 42 , wherein said structure is a boat, a vessel, an aquaculture equipment, an oil platform, a dock, a fishnet, a piling, or pier and components therefore.
