West Coast Triple Guard 1000 is a highly corrosion resistant coating that can triple the salt spray protection you are presently receiving. Although, normally used over zinc plated parts, West Coast Triple Guard 1000 can provide over 1000 hours of salt spray protection to red rust when applied over zinc plated and chromated parts, without destroying the aesthetics. West Coast Triple Guard 1000 minimizes abrasion of parts due to sharp edges, excessive part handling and/or tumbling.

Offers two to three times salt spray protection to white salts over that provided by the
     conversion coat (with .0005 plating thickness)
Extremely economical to operate
Can be applied to parts from most existing plating operations
No added costly equipment
Can be applied over many metals
Works over many different chromate films (all colors)
Unlike lacquers or paints, West Coast Triple Guard 1000 does NOT significantly change the
     overall thickness of the plated part
A more viable approach to extended corrosion protection than alloy plating

Zinc plated components vary from one industry to another. They share however, the most basic of metal finishing requirements: durable finish; aesthetically pleasant appearance; and cost effective processing. The designer and engineer must take into account several considerations to stay at the forefront of the finish potential. Not the least of which is the environmental regulations impact on the future of the selected finish. Zinc and Zinc alloys, such as zinc-nickel will surely play a more significant role as metals such as Cadmium are destined for the elements' Valhalla. Such sacrificial metals as Zinc, have significant corrosion resistance properties in spite of their apparent softness and propensity to scratching.

This specification covers requirements for electrodeposited zinc coatings applied to iron or steel articles to protect them from corrosion. It does not cover zinc-coated wire or sheets. High strength steels (tensile strength greater than 1700 MPa) shall not be electroplated. Stress relieve all parts with ultimate tensile strength 1000 MPa and above at minimum 190°C for 3 hours or more before cleaning and plating. Hydrogen embrittlement relieve all electroplated parts of 1200 MPa tensile strength or higher by baking at 190°C for 3 hours or more within 4 hours after electroplating. Supplementary treatments shall be in accordance with Recommended Practice B201. Type IV shall be in accordance with Recommended Practice D2092.
