Room Temperature, 65–85° F
Room-temperature black oxide processes are best for quick, safe, and convenient in-house and even at-home blackening. Use a room-temperature blackening process to give steel parts satiny, grey-black finishes and extra corrosion resistance.
Easy-to-use, room-temperature process for giving zinc parts and cadmium-plated parts a smooth, jet-black finish.
- Zinc and cadmium-plated parts
- Achieving smut-free finishes
- Mechanically plated zinc and cadmium surfaces
Hot Temperature, 150–180° F
Hot-temperature black-oxide processes produce glossy black-blue coatings and true black-oxide magnetite finishes in 10–20 minutes. EPi’s line of high-temperature blackeners offers impressive abrasion and corrosion resistance, and several products meet military and AMS specifications.
