SHIP BOTTOM PAINT AND NONTOXIC ANTIFOULING ANTIMICROBIAL WATER-REPELLENT ADDITIVE FOR PAINT

摘要

A nontoxic antifouling antimicrobial water-repellent additive added to ship bottom paints, etc., comprising a powder of calcium carbonate carrying silicone oil and absorbing silver nitrate. A small amount of the additive is added to a ship bottom paint, etc., and applied to a ship bottom, so that even when no toxic substance or the like is contained, attaching of various undersea lives, such as barnacles and algae, tending to attach to the ship bottom can be prevented effectively and efficiently for a prolonged period of time.
