What is MicroLok® AO?
An Attractive & Protective Finish for Iron & Steel – Without EPA Regulated Chemicals
Ideal for tooling and machine components, piston/cylinder assemblies, rotors & calipers, oil-field equipment or any part that does not require a dark black finish, but does require robust corrosion protection, anti-galling properties or break-in lubricity, without a dimensional change.
What is MicroLok® MZN?
An Attractive & Protective
Finish for Iron & Steel
The mil-spec compliant MICROLOK® MZN process is a fine-grained zinc phosphating solution for iron and steel components. MICROLOK® MZN provides corrosion resistance and anti-galling protection of high value components.
LUMICLAD® Black Oxide Process for Aluminum Alloys
A New Blackening Process for Aluminum
The LUMICLAD® Black Oxide process (patent applied for) is a new blackening method by which aluminum alloys can be coated with a durable and attractive black oxide finish. Utilizing a simple immersion tank process line, the LUMICLAD solutions carry out a two-stage chemical reaction to form an attractive, electrically conductive, satin-gloss black finish that is tightly adherent to the aluminum surface.
