The trivalent clear or blue bright products have been on the market and performing well for over 10 years now and the market has forced some of the yellow zinc plating to shift to the clear or blue chromates. Because of the history of the hexavalent yellow chromate and the performance and the appearance of the product, several industries are sticking to their guns and staying with the yellow chromates. At Saporito Finishing we want to offer our customers the best performing plating processes available and we have looked deeply into the trivalent yellow chemistries to attain optimum coating effectiveness.
The following data is a copy of our yellow trivalent matrix we utilized to find you the best performing yellow trivalent chromate over our zinc plate.
