Industry-Leading Products

EPi was the first to introduce a number of products to finishing and plating industry:

  • The first single-additive, inorganic-based brightener for cyanide copper plating: E-Brite 23-11R
  • The first single-additive brass-plating process: E-Brite B-150
  • The first bright leveling single-additive nickel-plating process: E-Brite 717

Electrochemical Innovations

EPi is proud of its latest product advancements:

  • E-Chrome™ Ultra Blue is a blue bright single-dip passivation with superior salt spray resistance to white rust to 150 hours.
  • E-PASSivate Yellow Red trivalent passivation also resists salt spray to white corrosion up to 250 hours. The color is comparable to hexavalent yellow.
  • E-Kleen SR provides better adhesion and brighter finishes by removing difficult-to-clean metal working fluids and carbonaceous smut from steel.
  • EPi is the only company to offer all three types of blackening processes—room, mid and high temperature—with the Kool-Blak 225 mid temperature process.


EPi has won numerous awards for the development of E-Brite 50/50, an alkaline non-cyanide silver-plating process that is a safer, cost-effective alternative to cyanide-based silver-plating processes:
