| MK-WS2-HT: Grease for High Temperature and Extreme Pressure Application: |
| |
Range: -20º C(-4º F) to 800º C(1472º F)
Made with High Viscosity Synthetic Base Oil, Tungsten disulfide particles and special additives.The Grease has Dropping Point higher than 320º C in the temperature range -20º C to 800º C
|
| |
The Grease has:
- Lowest Coefficient of Friction compared to other High Temperature Grease
- Excellent Extreme Pressure (EP) properties due to Tungsten Disulfide (WS2) particles
- High resistance to water, rust and humid environment.
- Excellent mechanical stability under high shear.
- EP properties and strong resistance to abrasion means the grease is ideal for high load and impact load applications.
- Ideal properties for Bearing Grease application.
- High dropping point which means it does not solidify at higher temperatures
