Manufacturers can now finish iron and steel components with MicroLok AO, a low temperature, environmentally friendly process that serves as a low-cost replacement for polluting cold blackening from Birchwood Technologies.
- Forms a non-toxic, aluminum oxide conversion coating that is 1.5 microns thick
- Silver/black in color
- Tightly adherent to the metal surface
- When sealed with a rust preventive, the finish provides robust corrosion protection that is better than cold blackening at half the cost, without undesirable pollution hazards
- Avoids the use of EPA regulated (copper & selenium) chemicals
- Contains no regulated chemicals
- Anti-galling protection to aid in assembly and start-up
- Temperature stability up to 1,400 F
- Safe 120-140 F operation with no boiling or splattering
