Castrol Molub-Alloy 777 ES greases are designed for very heavy duty service in extreme environments. They are blended and compounded to withstand heavy and shock loading, commonly found in the steel/primary metals, construction, mining, and forest products industries. Molub-Alloy 777 ES greases are made using a blend of high quality petroleum oils, polymers and Molub-Alloy lubricating solids. These lubricating solids work synergistically with chemical anti-wear and extreme pressure (EP) additives to reduce contact temperatures and wear while providing outstanding protection under extreme pressure and shock load conditions. Rust and oxidation inhibiting characteristics are maximised to afford effective rust protection and long life of the grease.
