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.
