Best Practices for Dupont Molykote 3402-C LF Anti-Friction Coating
-
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.
-
Application
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.
-
Curing
Coatings of Molykote 3402-C Anti- Friction Coating cure at normal room temperatures (20°C/68°F). The film dries to the touch in 10 minutes and cures in 2 hours. Accelerated heat cures can also be used. At 50°C (122°F), the coating cures in 10 minutes.
