InterCoat ChemGuard: A New Type of Corrosion Protection

More effective and less expensive than heavy-zinc galvanize

Published: Monday, November 20, 2017 - 12:00

(Chemcoaters: Gary, IN) -- Chemcoaters Inc., a coil coater and manufacturer of proprietary coating chemistries, has recently introduced InterCoat ChemGuard, 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 substantially improves corrosion protection on galvanized steel. For the last 70 years, the standard practice to protect metal from corrosion has been to coat it with zinc; using heavier zinc coatings to provide longer protection. This was the industry standard practice, until now. 

InterCoat ChemGuard 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 dramatically improve its corrosion protection properties. The bond is formed at the molecular level, and it cannot be washed or worn off. Because of this revolutionary process, InterCoat ChemGuard continues to protect during bending, stamping, welding, post-painting, and even shearing of the steel. With a low coefficient of friction, it actually enhances these processes. It also provides self-healing characteristics that help protect newly exposed zinc that naturally occurs during secondary processing. 

InterCoat ChemGuard is designed to be applied on the galvanize line or in custom formulas developed by the original coil coater and developer of this unique compound. 

InterCoat ChemGuard offers significant cost savings because it allows for lighter zinc to form the bond. It reduces the need for zinc coatings heavier than G30 that are used in many applications on the market today. The product also eliminates the need for temporary corrosion protection coatings often used in shipping and materials storage, including hexavalent chrome, a known carcinogen. 

The product is applicable to many industries including automotive, aerospace, and construction; this includes products such as electrical conduit, wall studs, furniture, fixtures, appliances, outdoor and highway railing, agricultural, lawn and garden products.

InterCoat ChemGuard is RoHS compliant. It is a major development for anyone looking to extend the corrosion resistance of galvanized steel.
