MOLYKOTE D-321 R Anti-Friction Coating
MOLYKOTE D-321 R is a dry-film lubricant available in bulk liquid or aerosol spray forms, designed for metal-to-metal contacts operating under high loads and slow to medium speeds. It's suitable for improving the running-in process and lubricating various components such as plain bearings, bushings, sleeves, power screw drives, threaded connections, fasteners, and high-voltage switches, even in demanding conditions. Application methods vary depending on the form; the bulk liquid requires thorough stirring before brushing or spraying, while the aerosol spray needs shaking before application of a thick, uniform coating. Proper surface preparation, including cleaning, degreasing, and optional phosphatization or sandblasting, is essential for optimal adhesion and service life.
The coating achieves touch-dry state within 5 minutes at 23 C, or 1 minute with 80 C hot air, and full curing is completed within 2 hours at 23 C. A recommended dry-film thickness of 5 to 20 m should be maintained for effective lubrication.
