UNIREX™ EP 2
Mobil grease , United States
Product Description
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.

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. |
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 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.
