An Indiana-based coil coater and manufacturer of proprietary coating chemistries has recently introduced a new type of corrosion protection for galvanized steel that utilizes covalent bonds and enhances the effectiveness of zinc.
Standard practice to protect metal from corrosion for approximately the last 70 years has been to coat it with zinc. Heavier zinc coatings have normally been applied to provide longer protection. In order to meet industry demand for corrosion-retardant galvanized steel, Chemcoaters, Inc, of Gary, Indiana, has developed InterCoat®ChemGuard, which forms a permanent, covalent bond on the surface of the metal. After application to a light layer of zinc, the product reacts with the zinc to dramatically improve its corrosion protection properties. The bond which is formed at the molecular level cannot be washed or worn off. This process 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.
InterCoat®ChemGuard is RoHS compliant and continues to protect during stamping, roll forming, shearing and is weldable, enhancing these processes due to a low coefficient of friction. It eliminates the need for temporary corrosion protection coatings, often used in shipping and materials storage, including hexavalent chrome, a known carcinogen, making it more environmentally friendly for all building, architectural, transportation and consumer appliance applications. It is applicable to many industries, including automotive, aerospace, construction, electrical conduit, wall studs, furniture, fixtures, appliances, outdoor and highway railing, agricultural, lawn and garden and other products using galvanize.
