How to Use Ultra-Blak Rectifier
Adding Ultra-Blak Rectifier to a black-oxide bath forces iron sludge or buildup to float to the top, making it easy to skim from the surface and remove the contaminants.
Use Ultra-Blak Rectifier to:
- Control the buildup of iron sludge and contaminants in black-oxide baths
- Decontaminate black-oxide baths in 10–15 minutes
- Avoid undesirable copper deposits and iron films
- Achieve purer, more beautiful black finishes
