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.

 

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.
