Ultra Supreme is compounded from the finest select high viscosity index solvent refined severely hydro-finished 100% paraffin base stocks and polyalphaolefin (PAO) synthetic base fluids available. Blended into these high viscosity index paraffin base stocks and PAO synthetic base fluid is an aluminum complex base thickener. This aluminum complex thickener allows the Ultra Supreme to exhibit excellent flow and film forming characteristics. This aluminum complex thickener allows the Ultra Supreme to exhibit the following performance features: •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 Supreme 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. •Low temperature pumpability characteristics. Further blended into the high viscosity index 100% paraffin base stocks, PAO synthetic base fluids and the aluminum complex thickener is molybdenum disulfide and a solid lubricant package. The molybdenum disulfide and solid lubricant package allows the Ultra Supreme to act as a "backstop" lubricant when the grease base is either destroyed or wiped away due to unexpected loads, start-up or other conditions which can exceed the capabilities of the grease base's fluid film lubrication. This "backstop" is created by the molybdenum disulfide's and solid lubricant package's natural affinity for metal surfaces. This natural affinity for metal surfaces allows the molybdenum disulfide and solid lubricant package to plate itself to these surfaces in order 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. The grease's 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 equipment, less downtime and extended lubrication cycles. Ultra Supreme has excellent rust and oxidation inhibiting characteristics, excellent water resistance, shear and mechanical stability, and good pumpability properties. Ultra Supreme also has superior cohesive and adhesive properties. Because of these cohesive and adhesive properties, Ultra Supreme will not wash out, pound out, splatter or squeeze out even under the heaviest loads or vibrations. Due to its superior cohesive and adhesive properties Ultra Supreme is not recommended for use in passenger car automotive wheel bearing applications. Ultra Supreme can be applied either manually or by a heavy -duty automatic lube system. Ultra Supreme has an operating temperature of -30°F to 350°F. Ultra Supreme #1 has an operating temperature of -10ºF to 350ºF. Moly Supreme #2 has an operating temperature of 0ºF to 350ºF. Moly Supreme #3 has an operating temperature of 30ºF to 350ºF
