One of EPI's strengths is developing custom formulations for its customers.
Today taking the formula off the shelf always does not work today as customers have individual needs. Barrett Plating challenged us to develop a hexavalent chromate that is blue without any yellow color and that has at least 72 hours salt spray. The EPi team of Larry Abbott Chemist and Sid Arthur Senoir Technical Service started working together in EPi's lab in New Berlin, WI. Through the testing, we actually found that the salt spray results exceeded 96 hours almost approaching 150 hours. This chromate is called E-Chrome 859. Another benefit of the E-Chrome 859 is that it produces a brighter blue finish. The E-Chrome 859 actually polishes the zinc plated surface.
