CRAX POST
Designed especially for use with CRAX BL processes, CRAX POST is an environmentally-friendly chrome-free post dip for electroplated trivalent chromium surfaces. It significantly improves the corrosion resistance of the decorative coating system. Performance in standard corrosion tests such as NSS and CASS is improved by applying CRAX POST on top of chromium layers electroplated from trivalent chromium electrolytes. The CRAX POST post-treatment does not affect part appearance.
