Chrome Plating Chemistry

Hard Chrome Plated RollsChromium plating demands increased efficiency and process control, at the lowest possible operating cost. Hunter Chemical LLC can help you meet these objectives with the use of our Hard Chrome Catalyst HCA-50™ and other chrome plating chemicals.

Hunter Chemical produces two types of catalyst chemicals used in Chrome Plating: non-fluoride concentrated catalyst HCA-50™ designed to deliver optimal efficiency as well as enhanced coating properties in functional (hard) chromium baths and fluoride-based HCA-80. Hunter also manufactures HCA Fume Suppressants which are South Coast Air Quality Management District (SCAQMD) approved for use in functional (hard) chromium, decorative chromium and chromic acid anodizing baths.

Hunter Chemical distributes chromic acid in multiple package options from inventory locations across the United States.
