DRAGONHIDE™ ZRE finish system is a duplex coating system engineered with a “self-healing” zinc-rich primer between the base metal substrate and electrocoat finish that dramatically improves the corrosion resistance of high-end underbody parts and sub-frame finishes on automobiles.
The SPECTRACRON® zinc-rich coating, which works exclusively with PPG’s POWERCRON® electrocoats to form the DragonHide ZRE finish system, has been performance-tested by major auto manufacturers for the past three years and achieved exceptional results. Potential applications are control arms, tie rods, linkages, engine cradles, fasteners and other components that are critical to the safety, durability and performance of automobiles.
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 finish solution can be applied by dip-drain, dip-spin and spray methods, and it offers various environmental benefits over competing coating systems because it is combined with an electrocoat layer.
