All about Solid Film Lubricants

What are they?

Sometimes described as "lubricanting paint,"solid film lubricants are a unique blend of a binder matrix and minute particles of solid lubricanting and rheological materials in a liquid carrier.

How do they work?

After application, the carrier evaporates, and as the resin cures ---either by air drying or oven curing ---it binds the solid lubricanting particles to the surface of the part. These lubricanting particles then prevent surface-to-surface contact and thus reduce friction and wear between mating surfaces.

Why use a solid film lubricant?

Bonded solid film lubricants were developed over 40 years ago to meet the unique problems of the then-emerging aerospace industry. They can be used where more conventional lubricants are ineffective or impossible, and they offer advantages other lubricants do not.

  • They lubricate effectively over a wide temperature range ---from -395゜to over 2000゜F ---where geases and oils are ineffective.
  • Some withstand loads in excess of 250,000 psi, and they typically exhibit a lower coefficient of friction as load is increased.
  • Solid film lubricants offer unique resistance to corrosion and chemicals.
  • In dusty, dirty environments they do not attract or hold contaminants.
  • Some are formulated to withstand even such extremes as radiation, a hard vacuum and liquuid oxygen.
  • Once applied, solid film lubricants require no maintenance.
  • They can be used on parts which are not accessible for relubrication.
  • Because solid film lubricants do not deteriorate over time, they are ideal for use on equipment operated only intermittently.

A few typical examples of where they are used

  • On parts that will come in contact with harsh contaminants such as chemicals, fuels and solvents.
  • Where adjacent parts could become contaminated with the migration of liquid lubricants.
  • On heavily loaded equipment susceptible to galling and seizing, particularly aluminum and titanium.
  • To prevent galvanic corrosion where two dissimilar metals have contact.
  • where dust or other airborne debris could become entrapped in wet lubricants and impair machine operation.
  • Where operating temperatures exceed the range of oils and greases.
  • To delay or prevent fretting corrosion.
  • On just about any moving parts ...
    fasteners, gears, cams, ball joints, bearings, slides, valves, levers, rollers, conveyors. The possibilities are virtually unlimited.

How are solid film lubricants applied?

They can be applied by spraying, dipping, brushing, spray/tumbling or dip/tumbling. Most solid film lubricants achieve optimum wear properties when applied to a total thickness between 0.0003 and 0.0005 inch, and when the lubricant is applied in very thin, multiple, uniform coats. This is best accomplished with the spray method. However, the size, configuration and other limitations of your component parts may dictate some other application method.
It is important to understand that solid film lubricants should be viewed as a system, taking into account the base material, the surface pretreatment, the method of application and the correct cure cycle. Eighty percent of all solid film lubricant failures are due to incorrect surface pretreatment and application; the rest are generally because the right lubricant was not selected.
Detailed processing bulletins and data sheets have been written to provide you with the correct pretreatment and application procedures for all the Everlube® solid film lubricants. They are available on request.

Everlube® solid film lubricants meet U.S. government and industry specifications

Because of their beginnings in the aerospace industry, many solid film lubricants are defined by and qualified to various military specifications. A large number of Everlube® products are also qualified to hundreds of specifications developed by major manufactures in the aerospace, automotive electronics, communncation and many other industries. You can get a complete listing by requesting Form 6060 from Everlube® Corporation.

Careful quality control

Each of our solid film lubricants is subjected to careful quality testing during every manufacturing step, and each batch is evaluated to ensure it meets all the prescribed criteria. We are always happy to provide certifications or test reports at the customer's request.

Technical service

Everlube® Corporation has capable and informed Technical Sales Representatives and Technical Service personnel available to help you select the proper product for your individual needs. We operate a technical service laboratory equipped to evaluate solid film lubricants for your current and proposed projects, and we can coat prototype parts for your test and evalution.

Environmental concerns

A growing number of state and local regulatory agencies are issuing very restrictive legislation to control emission of photoreactive solvent vapors into the atmosphere. Everlube® has developed solvent systems which meet the demands of many new regulatory requirements, and most of our products can be furnished with these special solvent systems.

Shelf life

Everlube® 's guaranteed shelf life for solid film lubricants is 6 months for those with water carriers, and 12 months for those with solvent carriers. Solid film lubricants should always be stored at room temperature (below 90゜) in a tightly closed container.
