Abstract

The disclosure described herein includes antifouling compositions, methods of antifouling by adhesion suppression and methods of selecting an antifouling composition which suppresses marine animal adhesion or reduces the strength of marine animal adhesion by reducing or quenching the oxidative adhesion chemistry of the marine animal.

First claim

What is claimed is:

1. An antifouling coating comprising:
an antioxidant coating coupled to surfaces submerged in sea water,
wherein the antioxidant is chemically unaltered by the coating,
wherein the antioxidant is present in the coating in an amount sufficient to suppress oxidant-induced marine adhesion and free radical-induced marine adhesion, and
wherein the antioxidant coating is one of a plurality of coats.

2. The coating of claim 1 wherein the coating adheres to surfaces submerged in sea water.

3. The coating of claim 1 , wherein the antioxidant coating is a top coat of the plurality of coats.

4. An antifouling coating comprising:
an antioxidant coating coupled to surfaces submerged in sea water,
wherein the antioxidant is chemically unaltered by the coating,
wherein the antioxidant is a reducing agent present in an amount sufficient to suppress oxidative-induced marine adhesion and free radical-induced marine adhesion, and
wherein the antioxidant coating is one of a plurality of coats.

5. An antifouling coating comprising:
an antioxidant coating coupled to surfaces submerged in sea water,
wherein the antioxidant is chemically unaltered by the coating,
wherein the antioxidant is one of a radical inhibitor and a radical quencher,
wherein the antioxidant is present in an amount sufficient to suppress oxidative-induced marine adhesion and free radical-induced marine adhesion, and
wherein the antioxidant coating is one of a plurality of coats.

6. The coating of claim 1 , wherein the antioxidant is BHT.

7. A method of inhibiting marine fouling comprising the steps of:
providing an antioxidant coating, wherein antioxidant is present in the antioxidant coating in an amount sufficient to suppress oxidant-induced marine adhesion and free radical-induced marine adhesion
applying the antioxidant coating to a surface, wherein the surface is configured to be submerged in sea water, and wherein the antioxidant coating is one of a plurality of coats, and
suppressing marine adhesion through reduction chemistry.

8. The method of claim 7 wherein the coating suppresses marine adhesion by reducing the strength of marine adhesion.

9. The method of claim 7 , wherein the coating is an evaporative coating.

10. The method of claim of 9 , wherein the evaporative coating is clean metal primer.

11. The method of claim 9 , further comprising the steps of:
providing the antioxidant which is soluble in a solvent of the coating and
dissolving the antioxidant in the solvent of the coating.

12. The method of claim 7 , wherein the step of suppressing marine adhesion includes the step of:
reducing or quenching oxidative adhesion chemistry of a marine animal.

13. The coating of claim 1 , wherein the antioxidant is selected from the group consisting of 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline (6-ethoxy), 2-tertbutyl-4-methoxyphenol and 3-tertbutyl-4-methoxyphenol (both described as “BHA”), 2,3-di-tert-butylphenol (“DTBP”), anisole, 1,2-dithioethane, pyruvic acid, ethoxyquin, and thioanisole.

14. The method of claim 13 , wherein the antioxidant is selected from the group consisting of 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline (6-ethoxy), 2-tertbutyl-4-methoxyphenol and 3-tertbutyl-4-methoxyphenol (both described as “BHA”), 2,3-di-tert-butylphenol (“DTBP”), anisole, 1,2-dithioethane, pyruvic acid, ethoxyquin, and thioanisole.

15. The method of claim 3 , wherein the antioxidant coating is only the top coat of the plurality of coats.

16. The method of claim 3 , wherein at least one coat of the plurality of coats, apart from the top coat, is an epoxy coating.
