Coventya (Brooklyn Heights, Ohio) now offers the Tristar 330 AF Process, its next-generation sulfate-based chromium decorative plating process for Coventya’s Tristar Trivalent Decorative Chrome Technologies line. Coventya says this new process outperforms present state-of-the-art technology while providing a deposit color similar to hexavalent chrome deposits.

Coventya designed the process components for effectiveness over a broad concentration range. A high rate of deposition allows the process to reach the required deposit thickness of 0.2 - 0.4 µm in 4 - 5 minutes at cathode current density ranges between 80 - 100 A/ft2 (861 – 1,076 A/m2).

The company says its Tristar 330 AF Process, in combination with its Tristar Shield Cr VI-free post-treatment process, results in a deposit corrosion resistance that satisfies the most demanding specifications for CASS and Neutral Salt Spray tests for steel and plastic parts, including sanitary-plumbing fitting components.
