ABSTRACT:
An improved method for preparing clay-based grease compositions is described whereby a clay containing pre-grease is prepared and a water separated from the clay-bearing pre-grease prior to the addition of an epoxide which is cured, e.g., simultaneously with the dehydration of the pre-grease. The grease compositions prepared in this manner show improved water resistance over those wherein the epoxide is added prior to separation of the water phase and the grease is also more responsive to the addition of conventional grease additives such as extreme pressure additives, anti-corrosion additives and anti-oxidants.
