Material Notes:
Mobilgrease XTC is an extra high performance product designed for use in high speed coupling applications. It is manufactured with a selected high viscosity mineral base oil and an extremely effective, heavy-duty additive package. Mobilgrease XTC is formulated to provide low bleed as well as high temperature stability, properties critical to modern coupling lubrication and protection. While the base oil provides excellent elastohydrodynamic lubrication (EHL) film protection properties, the additive package enhances the extreme pressure (EP) / anti-wear protection, rust and corrosion performance and the high temperature stability of this leading edge product. Mobilgrease XTC also incorporates proprietary formulation stability to outperform best-in-class low bleed coupling greases with respect to high temperature stability in high shear conditions. Mobilgrease XTC is an NLGI No. 1 lithium soap-base product. ExxonMobil research scientists formulated Mobilgrease XTC to meet or exceed the requirements of modern high-speed gear and grid design couplings including the AGMA CG-2 and CG-1 specifications. This grease has shown excellent performance and protection in a wide variety of coupling applications covering a broad range of industries. Based on its outstanding performance, this grease has become the product of choice for many coupling users. Mobilgrease XTC fully meets the performance requirements of major coupling manufacturers.Application Considerations: Because Mobilgrease XTC is highly viscous and has adhesive agents to address coupling demands, use of hand-operated grease guns at low ambient temperatures without auxiliary heat is discouraged. Mobilgrease XTC fully meets existing and AGMA Type CG-2 requirements for high-speed flexible gear and grid couplings. Mobilgrease XTC also meets less demanding AGMA Type CG-1 requirements. Mobilgrease XTC maintains its excellent performance characteristics in ambient temperatures up to 120º C. It is not recommended for temperatures below -30º C. Mobilgrease XTC is used widely in industrial applications requiring the use of: Grid-type flexible couplings; Gear-type flexible couplings
