Abstract

This report describes the history and present status of the development of a general purpose grease to be operational over a -l00 F. to +350 F. temperature range. These studies have been limited to development of greases thickened by colloidal calcium carbonate coated with calcium salts of aliphatic dicarboxylic acids. Using diester vehicles, it now appears probable that a balanced formulation can be made which will meet specifications for consistency, bleeding, work stability, dropping point, evaporation loss, low temperature torque, and water resistance. Some revision in composition of present greases will be required since incorporation of work stability and water resistance additives has been found to induce changes in consistency and bleeding which must be offset by slight changes in the thickener. In addition, an oxidation inhibitor must be incorporated prior to starting prolonged bearing tests at high temperatures.
