    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.


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