  • Air drying
  • Avoidance of stick-slip
  • High aging resistance
  • Fast air-drying and curing
  • Will not attract contaminants

Applications & Uses

Use Recommendations
  • For metal/metal combinations with slow to medium fast movements and high loads.
  • Suitable for the permanent lubrication of highly stressed sliding guides with low sliding speeds, oscillating movements or intermittent operation.
  • Improving the running-in process and for lubrication under high vacuum and at extreme temperatures.
  • Used successfully for cylinder-head bolts, toaster guides, car mirror adjustment mechanisms, high voltage switches, for the running-in of highly stressed gear wheel.
  • Emergency lubricant for parts of the rotor head of wind energy installations and for groove-free cold extrusion of steel.
  • Aerosol delivery allows for lubrication of hard-to-reach spaces
  • Excellent for lubrication of parts that experience high initial wear when
    breaking in new or rebuilt equipment.
How to Use

Surface preparation

First clean and degrease the surface which will be coated with Molykote® D-321 R Anti-Friction Coating. Phosphatization or sandblasting (180 grit) increases the adhesion and service life

How to apply

Stir Molykote® D-321 R Anti-Friction Coating thoroughly before applying by spraying or brushing.

Recommended dry film thickness: 5 to 20 µm.

Drying Time

After 5 minutes at 23°C the applied film of Molykote® D-321 R AntiFriction Coating is touch-dry; this process time can be reduced to 1 minute exposing the coated part to hot air at 80°C.

Curing time

After a curing time period of 2 hours at 23°C the dry film of Molykote® D-321 R Anti-Friction Coating can perform the best lubrication properties.

Solubility

Thinning can be carried out using Molykote® L 13 Thinner.
