复合磺酸钙润滑脂 CHEMTURA G2181, NLGI No.1.5/2

DESCRIPTIONG-2181-2is a member of a family of technologically advanced greases that have been developed by complexing modified overbased calcium sulfonates. This technology, developed and patented by Chemtura, is characterized by exceptional mechanical stability, high dropping point, high load carrying performance, reduced wear, and excellent resistance to water and corrosion. This technology equals and in many ways outperforms other premium, high temperature greases such as Lithium Complex, Aluminum Complex and Polyurea.

FEATURES AND BENEFITSThermal and Mechanical Stability

•Superior mechanical stability versus other thickeners, particularly in the presence of heat and water

•High dropping point, typically in excess of 300ºC

Load Carrying & Wear Protection

•Excellent EP and AW properties inherent in the thickener

•Does not require the use of additional additives

Resistance to Water

•Excellent resistance to water washout and spray-off

Corrosion Resistance

•Sulfonates are known and used for their excellent rust prevention properties

•This property is inherent in the thickener

•Will easily outperform all other technologies

Resistance to Oxidation

•The use of a premium antioxidant ensures excellent thermal and oxidation stability

APPLICATION AREASG-2181-2is a heavy-duty multipurpose industrial bearing grease. It is formulated with a high viscosity base oil package. It is specifically designed to perform well under the harshest conditions found in marine environments, steel mills, pulp and paper mills and other similar industries. It is ideally suited to applications where heat, water and extreme loads are encountered.
