Ultra-Blak 460 is a non-chrome blackening process that produces a decorative jet-black finish on zinc and zinc diecast surfaces.

Insta-Blak Z-360 is an easy-to-use, quick-finish room temperature blackening process for zinc and cadmium-plated parts. One gallon can coat approximately 200–300 sq. ft. of cadmium or zinc parts.
