Schaeffer Moly Ultra #221

Moly Ultra EP is a versatile, multi-purpose extreme pressure aluminum complex base grease that is specially formulated for use in all types of heavy-duty automotive, construction, mining, farming and industrial equipment and electric motor applications that are being used under the most adverse conditions of excessive pressure, high shock loading, extreme hot and cold temperatures, and moisture. Moly Ultra EP is compounded from the finest select high viscosity index solvent refined severely hydrofinished 100% pure paraffin base oils available.  Blended into these 100% pure paraffin base oils are an aluminum complex base thickener and selected additives.  This formulation provides Moly Ultra EP with the following outstanding performance features. 1. 2. 3. 4. 5. 6. 7. 8. Excellent pumpability characteristics for use in centralized lube systems. Excellent resistance to water washout and water spray off. Excellent shear and mechanical stability. Excellent anti-wear and extreme pressure load carrying properties. 100% reversibility.  This property allows Moly Ultra EP to have the ability to retain its grease-like consistency and remain in the bearings during periods of heat, high shock loading, extreme pressure, and severe mechanical action. Excellent rust and oxidation inhibiting characteristics. Excellent resistance to oxidation. A high dropping point. Incorporated into this blend of high viscosity index paraffin base stocks, aluminum complex thickener and selected additives is molybdenum disulfide.  The molybdenum disulfide provides Moly Ultra EP with the ability to act as a "back-stop" lubricant, when the grease base is either destroyed or wiped away due to unexpected loads, start-up or other conditions which exceed the capabilities of the grease base's fluid film lubrication.  This "backstop" is created by molybdenum disulfide's natural affinity for metal surfaces.  The molybdenum disulfide plates to the metal surface to form a long lasting solid lubricant film.  This solid lubricant film will withstand pressures up to 500,000 pounds per square inch, giving the metal surfaces of the bearings the protection they need during periods of high speed, high shock loads and extreme pressure. This solid lubricant film also helps to reduce friction. This reduction in friction results in reduced wear and a reduction in contact area temperature.  This in turn leads to increased bearing life, less downtime and extended lubrication cycles. Moly Ultra EP also has excellent adhesive properties. These excellent adhesive properties provide the Moly Ultra EP with the ability to resist washout, pound out, splatter or squeeze out even under the heaviest load or vibrations. Moly Ultra EP can be applied either manually or by a heavy-duty automatic lube system. Moly Ultra EP #1 has an operating temperature of -10ºF to 350ºF.  Moly EP #2 has an operating temperature of 0ºF to 350ºF.
