Insta-Blak 333

Samples Available *

A simple energy-saving process that produces a smut-free black finish unlike other blackening processes.

Recommended for blackening cold- and hot-rolled carbon steels, alloy steels, steel castings, cast iron, forged steel, and powdered metal. It will not blacken stainless steels. Can be used on sterling silver.

The Insta-Blak 333 Touch-Up bottle helps improve the appearance of scratches while avoiding the need to re-blacken the entire piece.

Ultra-Blak 400

Samples Available *

A superior high-concentration formula, the Ultra-Blak 400 easily produces an eye-appealing glossy black-blue finish on a wide variety of steel and steel alloys. This premium-grade black oxide is formulated with activators, catalysts, wetting agents, and rectifiers to produce a superior black color.

Requires ventilation for caustic fumes, boiling solution care, and pH adjust waste treatment system. Offers incredible abrasion resistance. Will not blacken cast iron or steel castings because they contain silica, resulting in a red-black color. Ultra-Blak 404 or Insta-Blak 333 can eliminate the red-black challenge. Meets military specification MIL-DTL-13924D and AMS 2485 H.

Ultra-Blak OX

Ultra-Blak OX is a concentrated liquid oxidizing agent for blackening steel that is combined with the black oxide finisher's sodium hydroxide, offering significant savings in chemical costs and freight.

A commodity chemical supplier can provide you with 50% by weight liquid sodium hydroxide. Blend 72% by volume of 50% by weight liquid sodium hydroxide with 28% by volume of Ultra-Blak OX the result is Ultra-Blak 400-L. Ultra-Blak OX can also be custom formulated to a specific oxidizer level.

Ultra-Blak Rectifier

Samples Available *

Liquid rectifier additive to control excessive buildup of iron and copper.

Ultra-Blak Rectifier aids in the removal of copper and red-iron oxide buildup during the blackening process of steel parts with and without copper brazing. Contaminations like these can produce red or copper films that make it difficult to produce a black color. Add rectifier to your black oxide tank and in 10–15 minutes, the iron will float to the top of the tank to be skimmed off and/or it will tie up the copper. The end result is less iron sludge buildup in your tank and beautiful black parts.
