How to use
Surface preparation
Carefully clean and degrease surfaces to be coated with MOLYKOTE® 3402-C LF Anti-Friction Coating.
Recommended pretreatments: blasting or phosphating. Both pretreatments increase the adhesion and service life of MOLYKOTE® 3402-C LF Anti-Friction Coating.
How to apply
Stir MOLYKOTE® 3402-C LF Anti-Friction Coating thoroughly before and during use, apply by spraying, dipping, centrifuging or brushing. Surfaces should be coated as evenly as possible. Recommended dry-film thickness: 5 to 20 μm.
Coverage
When applied at 10 μm dry-film thickness, MOLYKOTE® 3402-C LF Anti-Friction Coating has a coverage of approximately 12 m2/kg (this value does not take into account the losses generated during the application process).
Thinner
Recommended thinner is MOLYKOTE® L13 Thinner.
