UNIREX EP 2

UNIREX EP 2

Grease

Unirex EP 2 is a premium quality grease that combines advanced lithium complex soap technology and leading edge polymer enrichment technology to provide excellent adhesion, water wash-out resistance, mechanical stability and high temperature performance. Even after prolonged churning with water, Unirex EP 2 retains its consistency, adhesive and rust inhibiting properties. Unirex EP 2 provides good protection against corrosion and provides excellent extreme pressure protection against wear, even under severe shock loading conditions.

Unirex EP 2 is particularly useful in applications with severe water contamination. Unirex EP 2 is recommended for use in hand packed or grease gun applications, or in non-critical centralized systems, as well as grid-type flexible couplings, and is particularly suitable for use in vehicle wheel bearings.

Features and Benefits

Features 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.

Applications

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.
