The DYNASEAL™ series is a chrome free duplex coating system that combines an inorganic zinc-rich basecoat with either a fluorocarbon-based or an aluminum-rich organic topcoat. The DYNASEAL™ series are formulated to provide a high level of corrosion protection. The basecoat provides sacrificial protection of the steel substrate while the topcoat creates a durable barrier. These formulations are engineered with integrated friction modifiers to eliminate the need for sealers or post coating lubricants.
TYPICAL METHODS AND APPLICATIONS:
The DYNASEAL™ series can be applied by spray or dip-spin methods to a wide variety of substrates as well as engineering metals. Typical applications are for threaded and non-threaded fasteners, nuts, bolts, rivets, springs, and other miscellaneous hardware.
NOTE: DYNASEAL™ series coating is free of hexavalent chromium. In addition, this non-electrolytically applied process does not have any potential to induce hydrogen embrittlement.
