Coating Takes Corrosion Protection to a New Level

Thursday, December 1, 2016
 

PPG, Pittsburgh, PA, has introduced its DragonHide ZRE duplex coating, engineered with a self-healing zinc-rich primer between the basemetal substrate and electrocoat finish. The process promises to optimize the corrosion resistance of high-end automotive underbody parts and subframes.

Says product manager John Zbiegien: “When the barrier coat on an underbody assembly treated with the DragonHide ZRE system gets chipped by road debris, the sacrificial zinc-oxide layer corrodes, causing the basecoat to heal and protect itself. That enables highly exposed auto parts to last much longer in service than they do today.”

The zinc-rich coating has been performance-tested by major automotive manufacturers for the past three years and achieved exceptional results. Potential applications include control arms, tie rods, linkages, engine cradles and fasteners. The system also can be used for general finishing applications and by heavy-duty and military-equipment manufacturers for producing parts that must survive highly corrosive environments.

The DragonHide ZRE coating can be applied by dip-drain, dip-spin and spray methods.
