UNIREX™ EP 2
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.
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.
