APPLICATIONS
Molykote Z Powder can be used:
as a dry burnished (rubbed-on) lubricating film for metallic contacts
as a solid lubricant additive for self-lubricating plastics and sinter metal parts
as a solid lubricant additive in metalworking compounds
as a solid lubricant additive in brake lining application
as run-in aid, in press-fittings, in Heavy Loads and Slow Speeds applications and also in extreme environments (for example in dusty atmospheres or extremes of temperatures)
It is used in friction
Rolling bearings
Sliding bearings
Sliding guideways
Linear bearings
Enclosed gears
Cargo cables
Interference fits
Spline / key joints
Gaskets
