Additives User Benefits
Premium Grade Base OilSuperior grade, highly refined base oil resists oxidation, hardening and high-temperature breakdown to maintain better lubricity.
Calcium Sulfonate BaseWithstands high heat and provides additional extreme pressure protection under heavy loads. Extremely water resistant, heavier than water to resist washouts even in submerged environments.
Adhesive and Cohesive Polymers,Tackiness AgentsHighly-elastic polymers hold grease together and in place to reduce squeeze- out, channeling and sling-off. Prevents loss of lubricant that leaves bearings “starved”.
Rust and Corrosion InhibitorsBlocks out corrosive elements such as acids, water, condensate and steam by forming a protective barrier on equipment surfaces to prevent chemical wear.
Extreme Pressure (EP) AgentsA heat seeking additive that prevents the cold welding that can occur under heavy loads. Minimizes wear while helping equipment run cooler.
Anti-Wear and Friction Reducing AdditivesPrevents metal-to-metal contact, two-surface wear, vibration and chatter. Keeps high friction surfaces, such as bearings, properly lubricated to prevent metal loss, downtime, and replacement expenses.
Oxidation InhibitorsExtends lubricant service life by retarding the oxidation process. Provides a chemical shield that prevents the oxidizing effects of oxygen and water.
Shock Load ReducersCushions impact to minimize the stress, vibration and chatter that can occur under heavy loads and during start-stop operations.
Molybdenum DisulfidePlates metal surface asperities completely with a premium lubricant coating that withstands high pressures, heavy loads and shear conditions. Reduces abrasive wear, too.
GraphiteHigh concentration offers extreme temperature protection and stability while guarding against contaminants, heavy loads,and water washout.
