Description
Mobil Centaur XHP 462 grease is a premium greases formulated with advanced calcium sulfonate thickener technology.
The calcium sulfonate thickener carries both inherent rust protection and extreme pressure(EP) properties. Compared to conventional soap-base thickeners (i.e. lithium, aluminum, calcium soaps), the calcium sulfonate thickener used in Mobil Centaur XHP 462 excels in water saturated environments, providing rust protection between long re-lubrication intervals.
The inherent EP properties exhibit great stability in the presence of water, allowing a balance between wear protection and resistance to corrosion.
Mobil Centaur XHP 462 grease is particularly well suited to meet the demanding lubrication requirements of steel mill and paper machine equipment.
Mobil Centaur XHP 462 grease provide a balanced combination of water washout and water spray-off resistance, as well as excellent corrosion protection, in these severely wet environments.
