摘要:
The present invention provides a microorganism which, when an underwater structure is formed with a coating film containing it, produces a biojelly in water to prevent fouling of the structure with macroscopic aquatic life, such a coating or a coating film, and a method of preventing attachment of macroscopic aquatic life which comprises using said coating or coating film. The present invention is directed to a strain of microorganism belonging to the genus Alteromonas and having the ability to produce a biojelly.
摘要:
A method for preventing settlement of aquatic fouling organisms on surface of an aquatic structure without environmental hazard is provided. The method is based upon absolutely novel concept to prevent the settlement by means of thick slime layer, i.e. bio-jelly, deposited on said surface. The present invention also provides a bio-jelly producing agent and a bio-jelly producing paint both useful for the present method. Further, the present invention provides a novel low toxic antifouling agent.

摘要:
The present invention provides a nonelution type antifouling method which comprises applying a nonelution type antifouling coating composition comprising at least two resins insoluble in seawater and incompatible with each other on top of the outermost layer of underwater portion of a marine structure and forming a coating film having a microheterogeneo us structure in which granular or disk-like minute protrusions with a mean size of 10 nm to 20 &mgr;m in diameter comprising at least one of said resins occupy 5 to 49% of the surface area of the coating film.
摘要:
An antifouling coating composition which comprises at least two kinds of mutually incompatible resin compositions and which is capable of forming a microheterogenous coating film having a multiplicity of spherical or disk-like minute protrusions comprising at least one of the resin compositions,at least one of the resin compositions to yield the spherical or disk-like minute protrusions being produced from an antifouling monomer and an ethylenically unsaturated monomer copolymerizable therewith.Since the antifouling coating composition of the present invention contains a resin composition adapted to impart an antifouling effect to the coating film, it displays a long-term antifouling performance beyond the antifouling effect attributable to only said microheterogenous structure.
