Chemcoaters, Inc., a coil coater and manufacturer of proprietary coating chemistries has recently introduced InterCoat ChemGuard, a new type of corrosion protection for galvanized steel.
InterCoat ChemGuard uses a new type of coating technology that utilizes covalent bonds and enhances the effectiveness of zinc and improves corrosion protection on galvanized steel. 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.
InterCoat ChemGuard, instead, reacts with the zinc to form a permanent, covalent bond on the surface of the metal. The product is applied over a light layer of zinc, which reacts with the zinc to improve its corrosion protection properties. The bond which is formed at the molecular level cannot be washed or worn off. "This is different and more effective than the typical barrier coating," said a company spokesperson. "This revolutionary 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."
The product is RoHS compliant and continues to protect during stamping, roll forming, shearing and is weldable. With a low coefficient of friction, it actually enhances these processes. InterCoat ChemGuard is designed to be applied on the galvanize line or, for custom formulas, by the original coil coater and developer of this unique compound.
It is suitable for 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.
