Lithium Complex Thickened Grease shows Improved Water Resistance with Addition of Bismuth Carboxylate
- PAPER # 0208 -
Water washout characteristics and mechanical shear stability were investigated in a lithium complex thickened grease formulated with a bismuth carboxylate. Test results indicate that the water resistant properties of the lithium complex grease were enhanced by the presence of the bismuth carboxylate. The data also shows that the improvement in water resistance is relatively unaffected even when the acidic carrier of the bismuth carboxylate is neutralized.
