Our products feature molybdenum disulfide formulated for specific applications.

Molybdenum disulfide is a solid lubricant. We use only American made moly, which is processed from molybdenite ore mined in the State of Colorado. Its excellent lubricating capabilities were recognized by pioneers in the 19th century who smeared the ore on the axles of covered wagons as they migrated westward.

This unique solid lubricant was developed in the 1930's, but not until the 1950's did full scale use of moly begin.

Considerable scientific research has been done on moly and its lubricating properties. Our formulas make use of that research, of bench tests on our products and other products, of our years of experience with moly, and of anecdotal reports on performance.

Molybdenum disulfide has a "lamella structure." An atom of moly (Mo) has an atom of sulfur (S) on the top and bottom of it; hence the chemical symbol MoS2. In application the moly aligns itself in platelets. The sulfur atoms have a loose bond with each other, which accounts for the "slipperiness" of moly. The molybdenum atom is an element that withstands extreme pressures, which accounts for the load carrying capability.

Moly has an affinity for steel. (Moly also works well with many other kinds of metals.) It fills in the microscopic pores and plates out over the surface creating a barrier film of about 1.5 microns. In use, the molecules slough off at the surface of the film and are instantly replaced by other molecules from the reservoir of moly in the lubricant.

The benefit is less metal to metal contact between the two sliding surfaces. Less contact means a reduction in friction and wear. This protection is especially valuable in the presence of heat, moisture and pressure. Both heat and moisture lower the viscosity of oil (making it "thin"), which reduces the thickness of the film of oil and makes it less able to keep the two opposing sliding surfaces separated.
