FEATURES

Excellent protection against fretting wear and corrosion
Extends service life
Low friction
Lubricate beyond the yield point of most metals in boundary applications, reducing wear and helping to prevent seizing, galling and excessive friction
Aid run-in and reduce frictional force and surface damage
Low coefficient of friction allows for effective conversion of torquing force into holding force;
reduces the force required for disassembly of threaded fasteners

APPLICATIONS

Molykote G-n Metal Assembly Paste lubricates surfaces subjected to extreme pressures. Specific applications include:

Running-in lubricant – for new or rebuilt equipment, such as gears, splines,
journal bearings, cams and ways
Metalworking – helps prevent galling, welding and metal pickup on tools and
dies in machining, stamping, and drawing operations, tube bending, thread
rolling, cold heading, swaging and forging
Assembly lubricant – reduces torque in tightening threaded fasteners and tension variation from bolt to bolt; eases disassembly and reduces chance of damage
Helps prevent fretting wear and corrosion, and cold welding of bearing shafts, bushings and splines
Press-fitting lubricant – allows press fitting without chatter or stick-slip in most cases; reduces the force required for interference fitting and minimizes distortion

Molykote G-n Metal Assembly Spray is primarily designed as a running-in lubricant for plain bearings, splines, gears, cams and ways, and because of its low coefficient of friction, as a lubricant for movable screws, threaded spindles and lead screws. It can also be used wherever protection against friction and high load conditions is needed, where burnishing is impractical, or where a paste in aerosol form is desired. It is suitable for airframe and aircraft engine applications.
