Mobil Centaur XHP 460 Series greases are a superior family of greases developed with advanced calcium sulfonate thickener technology. Calcium sulfonate thickener provides rust protection and extreme pressure (EP) properties. Compared to conventional soap-based thickeners (lithium, aluminum, calcium soap), the calcium sulfonate thickener used in the Mobil Centaur XHP 460 Series excels in water-saturated environments by providing rust protection during extended relubrication intervals. Mobil Centaur XHP 460 Series greases are specially developed to meet the demanding lubrication requirements of iron and steel mills and paper machine equipment. Mobil Centaur XHP 460 Series greases provide excellent corrosion protection in these extremely wet environments, as well as a balanced combination of washout and spray resistance. The calcium sulfonate thickeners used can retain their structure and EP protection properties even at high levels of water contamination.
