THE BLACKENING PROCESS: INSTA-BLAK 333

For the longest-lasting, deepest, and cleanest black finishes, we recommend the following blackening process. Please read all safety data sheets and technical data sheets prior to beginning a project.

1. CLEAN

Soils such as cutting oils, coolants, lubricants, and rust inhibitors must be removed from the metal workpiece. Soils can inhibit the blackening process and negatively affect coating adhesion and appearance. Clean the parts prior to beginning the blackening process. 

Recommended Cleaning Products:

E-Kleen SR 148-E is an aqueous alkaline soak cleaner that removes carbon smut from steel and metal parts, resulting in better adhesion and brighter finishes. It’s ideal for soak cleaning.
