Molybdenum Disulfide


Uses for these coatings are varied and numerous. Progressive and innovative engineers will find answers to many of their lubricating problems through the use of these coatings.
Some general applications are for:

Electrical and mechanical equipment that might be functionally impaired or contaminated by liquid, powder, or grease lubricants.

Surfaces that must maintain good lubricity in a wide range of temperatures, under high loads, at high speeds or in combinations of these conditions.

Equipment whose design may require lubrication in inaccessible areas.

Parts coming in contact with dust or other contaminants that might adversely affect other lubricants.

Use where solvents or other liquids might be reactive with oil or grease causing loss of lubricity and possible part malfunction.

Parts which frequently require oiling or greasing. Examples of specific applications are on such items as studs, nuts, bolts, valve parts, airborne mechanisms, non-stick surfaces in molds and on any other items with bearing surfaces or moving parts. IMF 1 can be applied to rubber (such as gaskets and “O” rings), stainless steel, brass, aluminum, cold rolled steel, chromium and most other metals.

Below are two innovative molybdenum coating systems IMF has developed. 

IMF-1

This system utilizes dry lubricants: molybdenum disulphide, graphite, or other solid materials in a suitable binder. This system offers a combination of properties including high bearing strength and lubricity. It can be used in a wide range of service temperatures. Depending upon selection, these coatings operate in extreme heat and excessive cold (-450ºF to +2,000ºF). They may also be chosen to operate at high speeds (to 30,000 R.P.M.) and under high loads (to 250,000 P.S.I.). IMF-1 coatings prevent wear, seizing, galling, and fretting corrosion. They have a coefficient of friction range of .04 to .08. Nominal thickness of the coating can be controlled from .0002” to .0005”. Some parts having areas difficult to cover may receive more coating thickness due to spraying patterns required to obtain a “holiday free” application.

IMF-2

This multilayer thermosetting coating system designed to impart lubricity to coated parts as well as provide good corrosion resistance in a wide range of severe environments. This coating system operates under high heat and in subfreezing temperatures (-300ºF to +450ºF). The IMF-2 coating system will withstand bearing loads up to 80,000 P.S.I.

On conventional steels the accepted commercial practice is to phosphate coat as a first step. The intermediate coat utilizes specially formulated epoxy coatings. The finish coat usually contains graphite and/or molybdenum disulphide in a thermosetting resin. The finish coat is designed to impart lubricity to the part with a friction coefficient range of approximately .04 to .08. Total coating thickness of .001” to .002” can be maintained depending upon the configuration of the part being coated. Where close mechanical tolerances are a factor, it is recommended that the user discuss special requirements. Use of this coating is indicated where lubricity and long life in corrosive atmospheres is needed.
