Coating Enhances Zinc Protection on Galvanized Steel

Chemcoaters Inc. offers InterCoat ChemGuard, a coating designed to enhanced the effectiveness of zinc and provide improved corrosion protection on galvanized steel. According to the company, heavy zinc coatings have typically been used to protect metal from corrosion. The InterCoat technology is applied over a light layer of zinc and reacts with it to form a permanent, covalent bond on the surface of the metal that cannot be washed or worn off. This allows bending, stamping, post-painting and even shearing while providing self-healing characteristics that help protect newly exposed zinc that naturally occurs during secondary processing, the company says. The product also is said to eliminate the need for temporary corrosion protection coatings often used in shipping and materials storage, including hexavalent chrome.
