Dry Film Lube (DFL)
Dry Film Lubrication, also known as Solid Film Lubrication (SFL) or Anti-Gall, uses a dry substance or coating to reduce friction between two surfaces. This low coefficient of friction (0.04), makes them ideal for applications that need extended wear resistance, have marginal, or no lubrication options.
Dry Film can help minimize wear and tear while also increasing efficiency in a mechanical
system. It is commonly used in applications where high heats can break down conventional lubricants such as oil or grease, and for assemblies which may be stored for long periods in non-climate controlled warehouses – yet will still meet form, fit, and function of a newly coated component.
Benefits:
- Improves sliding wear
- Excellent corrosion resistance
- Helps prevent galling & seizing components
- Reduces high operating temperatures due to excess friction
- Aids against inefficient mold release/mold flow
- Reducces component failure that leads to downtime and costly repairs
Material Properties:
THICKNESS:
Typically application-specific but is often in the range of 0.0002 to 0.001 inches per surface
SUBSTRATES PLATED:
Ferrous and non-ferrous metals, rubber, and glass, provided proper surface preparation is followed
Industry Specs:
AS 1701; AS 5272; AS 5528; MIL-L-46010; MIL-L-46147; MIL-PRF-46010; MIL-PRF-46147
