ABSTRACT:
This invention consists of a coating that is zebra mussel resistant and biofouling resistant without dependence on copper leaching. The coating is a solid solution of copper and nickel containing at least 65 percent copper. Application of the coating to stationary screens, traveling water screens, trash racks, louvers, and other components of water withdrawal and hydroelectric systems, netting and other porous materials used in barrier nets, fish nets, aquaculture, and fish hatcheries, the bottoms of water craft including recreational craft, boats, and ships and on bouys, piers and pilings and other materials that might benefit from resistance to the attachment of zebra mussels and other aquatic or marine organisms. Unlike coatings that depend on release of copper or copper ion for resistance, the rate of copper and copper ion release into the surrounding waters when measured using NSF International standard leach testing protocol and USEPA certified testing procedures is below the practicable detection limits of the equipment of 50 parts per billion.
