Theory behind Mr. MOLY Lubrication

Mr. MOLY products utilize the naturally occurring lubricant, molybdenum disulfide, along with other selected minerals and chemicals in the most effective way possible for industrial, manufacturing, mining, marine, agriculture, and automotive applications.

In use, Mr. MOLY products form a lubricating layer of molybdenum disulfide on metal-to-metal surfaces, reducing friction, wear, and operating temperature. What makes Mr. MOLY unique is the .05 micron particle size of molybdenum disulfide in our lubricants. The small particle size prevents Mr. Moly from being filtered out by even today’s hybrid automotive filters and keeps the MOS2 in suspension indefinitely. 

The molybdenum disulfide molecules in Mr. MOLY arrange themselves into layers into which each molybdenum atom is sandwiched between two sulfur atoms. The sulfur atoms are attracted to metals and therefore become plated or bonded on to each of the adjacent bearing surfaces. In between these two platings, further layers of molecules form. The sulfur-to-metal bonding is very strong, but the sulfur-to-sulfur bonding between adjacent molecules is very weak, allowing molecules to slide freely over one another. In this way direct contact of metal-to-metal surfaces is prevented and friction is considerably reduced. Consequently, local heating and wear is inhibited and protection is achieved even under extreme conditions of pressure and temperature.

The molybdenum disulfide plating is, in effect, a separating layer of immense strength, greater than the yield stress of most metals...and in addition it possesses the low coefficient of friction of .03 to .06 which gives more efficient lubrication combined with greater protection.
