BLACK OXIDE

Insta-Blak 333 is an immersion/swab on blackening solution that results in a smooth, no-smut satin black finish on tools and architectural surfaces. One gallon of un-diluted Insta-Blak 333 concentrate can coat approximately 400–500 sq. ft. of metal parts.

Insta-Blak 333 GEL is a slower-acting blackening process for steel and ferrous metals. This gel-based solution is ideal for simple swab-on vertical applications, touchups, and the user who prefers a slower blackening reaction. 

Ultra-Blak 404 oxidizing salts are used to blacken cast iron, malleable iron, and some mild low-carbon steels with a deep, rich black finish.

Ultra-Blak 466 is a non-nickel, two-component liquid concentrate solution that produces a decorative black finish on nickel surfaces.
