Corotac 500/1000

COROTAC 1000 was specifically developed to provide corrosion and chemical resistance for automotive components in the Northern Hemisphere where the salting of ice roads dictates the highest possible protection be given to automotive components.

The multi layer system of thermosetting aluminium pigmented, epoxy coatings applied over a yellow dichromate passivated Zinc Plate. The typical film thickness for the coating systems when applied to fasteners is in the range of 10 – 25 microns. This thickness of coating provides a minimum of 1000 hours protection to salt spray when tested as per ASTM B-117.

COROTAC 1000 is also resistant to all automotive fuels, a wide range of organic solvents, acids and bases.

Although developed for the automotive components market, in other industrial applications the coating systems can be applied to provide exceptional corrosion protection for use in the most extreme environments.

TYPICAL CHARACTERISTICS:
