Dry Film Lubricant for Aerospace
Originally developed for NASA, Dicronite® has been used to keep mechanical systems for aviation/aerospace reliable and precise. The coating provides precision friction reduction and ensures reliability in some of aerospace’s toughest environments.

Dicronite® Coating
Aerospace Engineers use Dicronite® when:
- extreme high or low temperatures limit the function of other lubricants
- a vacuum environment prevents the use of other lubricants
- precision tolerances must be maintained
- friction is causing galling between components during installation/assembly
- there is too much resistance in the motion of an assembly
- a need to maximize performance of a component
- sliding wear is limiting component lifetime
- trying to avoid costly redesign

FAQ
Most frequent questions and answers
Yes. If you call out the specific areas that Dicronite® is prohibited, we can mask accordingly.
We have a facility that is both ITAR registered and Nadcap certified.
Our standard process conforms to SAE-AMS2530, so we can process all orders with drawings calling out this spec. DOD-L-85645A was canceled and superseded with SAE-AMS2530 by the Department of Defense, so all callouts of DOD-L-85645A flow to the requirements of SAE-AMS2530. We can process orders with either callout!
Wear is a system effect, so it can be difficult to estimate the lifetime in each application. Dicronite® should be used for applications where sliding wear is present, but not abrasive wear – this is too aggressive for the soft, lubricious Dicronite® coating. In applications where an extensive wear life is required, it is common for Dicronite® to be applied on top of a hard, wear resistant coating.
We recommend testing to ensure Dicronite® is sufficient for your application and are always happy to coat a small order of parts to support your testing!
Dicronite® can be applied to all metals, most plastics, and some ceramics. In addition, Dicronite® can be applied on top of many other coatings or platings such as Nickel, Zinc, Chrome, Anodize, DLC, and more.
Dicronite® provides only minor corrosion prevention. However, many customers use Dicronite® on top of coatings or platings that do prevent corrosion for combined corrosion resistance and friction reduction.
We recommend cleaning coated surfaces with isopropyl alcohol or mineral spirits, but other solvent or solutions may also be used. Avoid using cleaners that are very acidic or basic.
If wiping coated surfaces, use a soft cloth. Note that when wiping a coated surface, you may find a residue coming from the part – this is normal. It is not necessary to wipe the coated surface until no residue is wiped from the surface. The coating naturally “smudges” or “smears” as part of its ability to lubricate.
Coated parts should be handled to prevent physical damage to coated surfaces such as scratching, scraping, or abrasion. In addition, parts should be stored in a manner that prevents corrosion of the underlying substrate. If the part begins corroding underneath the Dicronite® coating this can diminish the performance of the coating.
Aerospace dry lubrication for 65+ years.
Dicronite® is a dry film lubrication made up of tungsten disulfide.
It can be applied to all metals, most plastics and some ceramics; may be applied on other coatings and platings as well.
COATING THICKNESS – 0.5 micron (0.00002 inch) or less
THERMAL STABILITY – up to 538°C in air; 1316°C in vacuum
COMPATIBILITY – compatible with greases, oils, fuels, fluids, and many solvents.
Dicronite® is applied at one of many worldwide licensed coating facilities.
After surface preparation, Dicronite® is impinged onto the surface at high velocity.
The material includes no binders or adhesives and requires no curing.
