According the NLGI annual production survey, Calcium Sulfonate Complex Grease continues to grow in popularity year-over-year around the globe. From steel mills to food processing plants; from marine decks to nuclear power plants; the technology has found application in most settings that call for grease lubrication. It continues to find its way into new and interesting settings. Its inherent properties of corrosion resistance, extreme pressure and antiwear performance, its high dropping point, good water resistance and excellent mechanical stability make it an ideal choice of product where a grease will encounter heat, water and high loads. This presentation will provide a good overview of the technology, from differences in manufacturing to its inherent properties. It will also look at several applications where it has provided great benefit.
