Simple Process, Superior Finish

Clean, Deep Finish: No smutty rub-off as with other room temperature blackening processes. Insta-Blak 333 produces a super-deep, rich blackness and corrosion resistance equal to hot black oxide. There is no white salt bleed-out as is common with hot black oxide. For more information check out our Black Oxide FAQ.

5 Step Process: The most commonly used process in commercial blackening includes seven steps; however, the Insta-Blak process in most installations requires only 5 steps. Click for our free metal blackening guide (PDF)

High Productivity: Parts can be blackened in two minutes vs. 15 to 30 minutes for hot black oxide. Twice the amount of parts can be blackened in the same amount of time. Insta-Blak 333 has a wide operating window and produces the same results at 10,15, or 25 percent concentrations making it practical in automated finishing machines.

Versatility: Blackens many different types of metals including cast iron, forged steels, mild steels, hardened steels and powdered metals.

Convenient: Easy to do in-house. No need to heat blackening solution. Ideal for high volume or short run projects
