Product Description
Mobiltac 375 NC, 325 NC ａnd 275 NC extra high performance non-leaded, diluent-type, heavy-bodied open gear lubricants designed for a wide variety of open gear ａnd mining applications. They contain a non-chlorinated, volatile solvent that ensures fluidity during application, even at low temperatures. Once applied, the diluent evaporates ａnd the lubricants take on a flexible, adhesive, high-strength consistency that is maintained throughout their service life. Mobiltac 375 NC, 325 NC ａnd 275NC adhere strongly to gear teeth ａnd other machine elements to resist excessive throw-off, thereby providing a wear-resistant, viscous, continuous film that lubricates well under boundary conditions. Mobiltac 275 NC also contains solid phase EP/anti-wear additive for added equipment protection
Mobiltac 375 NC, 325 NC ａnd Mobiltac 275NC will not harden, chip, or flake in cold weather, are self-healing, ａnd do not form a hard-packed buildup in gear-tooth roots. Dripping ａnd throw-off are minimal, ａnd the lubricants are easily cleaned up with a solvent-soaked rag. The lubricants provide resistance to rain, snow, ａnd process water washing. Their flash points minimise the risk of fire. These new generation gear ａnd mining lubricants are applied easily by hand or by automatic dispensers. Mobiltac NC technology has rapidly become a firm favourite among many open gear users ａnd mine operators around the world

Applications
Mobiltac 375 NC, 325 NC ａnd Mobiltac 275NC are designed for use in a wide variety of open gear ａnd mining applications:
- Mobiltac 375 NC, containing a high-viscosity base oil, is recommended for the lubrication of highly loaded open gears, including those that operate at high temperature, for example, ring gears on cement kilns ａnd large gears on ore-processing mills
- Mobiltac 325 NC is recommended for the same applications as Mobiltac 375 NC. It contains more diluent ａnd has a lower viscosity for ease of application at cooler temperatures
- Mobiltac 275 NC is designed for service as a lubricant for mine ａnd quarry shovels, draglines, ａnd related equipment; also open gears, racks ａnd pinions, swing gears, booms ａnd sticks
- Minimum operating temperature for Mobiltac 325 NC is -18 C, 375 NC is -1 C ａnd 275 NC is -9 C
