MOLYKOTE 7400 Anti-Friction Coating
MOLYKOTE 7400 is a water-based, air-curing dry lubricant designed for metal-to-metal contact situations experiencing slow to moderately fast movement under high loads. This coating is particularly beneficial for enhancing the break-in period of gearboxes, sliding bearings, and guides, providing maintenance-free, permanent lubrication in low-speed or oscillating applications where traditional oil or grease lubrication is impractical due to design constraints or contamination risks. The coating's formulation ensures high load-carrying capacity and a low coefficient of friction.
Application involves cleaning and degreasing the surface, with optional phosphatization or sandblasting (180 grit) for improved adhesion and longevity. The coating is applied via spraying, dipping, centrifuging, or brushing to achieve a dry-film thickness of 5 to 20 µm. Curing time varies depending on temperature: 40 minutes at 23°C, 10 minutes at 50°C, or 5 minutes at 90°C (object temperature). The coating contains solid lubricants, an inhibitor, an organic binder, water, and stabilizers, and is free from flammable solvents.
