Modern Plating’s research has developed Zinc-PLUS 3 to meet the needs of those customers requiring the high performance of Modern’s popular Zinc-PLUS finish but in a trivalent version. All drive characteristics of our hexavalent Zinc-PLUS finish have been maintained in the new trivalent Zinc-PLUS 3 finishes.
Zinc-PLUS 3 clear will surpass 300 hours to the first sign of white corrosion in neutral salt spray testing and 1,000 hours to the first sign of red corrosion. Zinc-PLUS 3 black will also surpass 300 hours to the first sign of white corrosion in neutral salt spray testing and over 720 hours to the first sign of red corrosion.
Zinc-PLUS 3 meets the demanding specifications of the automotive and other industries that require superior performance. Zinc-PLUS 3 offers a medium to high gloss finish, good elasticity and minimal recess fill. This permits it to be used on a wide variety of part configurations. Zinc-PLUS 3 offers significant cost savings when compared to other finishes offering this level of corrosion resistance. It meets all the adhesion requirements of the ASTM B-571 standard and has passed the climatic/cyclical testing of GM 9540P.
