Advantages and Potential Benefits

Formulated using an advanced lithium complex soap thickener

Enables longer grease life at higher temperatures than possible with greases made with most other soap types.

Excellent EP and anti-wear properties

Equipment protection and potential equipment life extension even in severe operating conditions.

Potent corrosion protection

Guarding equipment against rust and corrosion in heavy duty and automotive applications.

Excellent resistance to water washout and spray-off

Uses new polymer technology. This enhances the product’s already excellent adhesion tendency and water washout resistance. Ensures proper lubrication and protection even in hostile wet environments.

Certified against NLGI service classification GC-LB

One grease for wheel bearings and chassis lubrication as demonstrated against all NLGI GC-LB performance tests.


Unirex EP 2 is an excellent multipurpose grease for heavy-duty service in both Automotive and Industrial applications. Its excellent water resistance and extreme-pressure protection exceed the performance levels of conventional multi-purpose light-to-medium-duty greases.

Unirex EP 2 exceeds the requirements of the ASTM D 4950 GC-LB grease classification for automotive wheel bearing and chassis applications.

Unirex EP 2 is particularly well-suited for general purpose anti-friction bearings operating at high temperatures. In addition, its low oil-bleed properties offer a distinct advantage where minimal leakage is critical.
