The InterCoat ChemGuard family of stand-alone coatings and hybrid pretreatments is highlighted by the ChemGuard 300 Series, a RoHS-compliant (hexavalent chrome-free) coating that features the unique chemistry of trivalent chromium vs. the standard hexavalent chromium used for decades in the metals coating industry. With comparable or, in many applications, superior corrosion resistance to hexavalent chrome treatments, this coating bridges the long-standing divide between performance and environmentally-friendly product in the market.
InterCoat ChemGuard is a highly corrosion-inhibiting and adhesion-enhancing coating technology that creates a permanent covalent reaction with any zinc or zinc-alloy coated substrate. Used as a hybrid pretreatment, the product enhances corrosion resistance in a 20 percent to 50 percent thinner coating onto the substrate, while exceeding the prevalent corrosion standards in industry, ASTM A1003/A1003M.
Since its development in 2011, the InterCoat ChemGuard family has grown to include a RoHS compliant trivalent chrome product with many color tinted versions of the product now available.
Used as a pretreatment, InterCoat® ChemGuard is an ideal complement to pre- and post-paint, powder and other surface coating requirements.
Originally developed for the metal stud and other building/construction applications, InterCoat ChemGuard coatings are now used extensively in end products for the transportation (automotive, bus, truck and RV), consumer products (appliance, power-gen, and HVAC), agricultural and off-highway vehicle markets, among others.
