Description

Gulf Crown USG 2.5 is a lithium-calcium thickened lubricating grease based on mineral base oil and contains extreme pressure/anti-wear additives, anti-oxidants, corrosion inhibitor and also contains polymer to enhance adhesion. Gulf Crown USG 2.5 in marine applications outperforms traditional calcium and lithium greases with respect to water resistance, temperature range, mechanical stability and load carrying capacity. Gulf Crown USG 2.5 has enhanced rust protection, excellent load carrying capacity, good oxidation stability and outstanding water resistance. Gulf Crown USG 2.5 is used for the lubrication of rudders, steering quadrants and other bearings and gears on board of ship, including fish sorting machines, anchor winches and stern tubes. "One single grease for all lubricating points on board". Gulf Crown USG 2.5 is also suitable for heavily loaded industrial applications where water wash out is problematic and for heavy-duty vehicles working outdoors in wet and dirty conditions.
