NYEBAR T SERIES
A barrier film that inhibits oil migration
Description
NYEBAR barrier films inhibit oil migration in mechanical devices and prevents environmental fouling of electric components and printed circuitry.
Advantages
- Inhibits oil creep to prevent oil migration and contamination.
- Wide temperature performance up to up to 200°C
Applications
NYEBAR barrier films are most commonly used whenever lubricant migration is a concern including:
- Bearings & actuators
- Optics
- Connectors & potentiometers
- Release agents
- Fluidics
Applying NYEBAR
NYEBAR should not be applied in the area requiring lubrication, but rather as a dam or barrier around that area. NYEBAR can be applied to any clean metal, plastic or glass surface by:
- Dipping the component in the solution
- Spraying the solution on the part
- Brushing small areas of a device
Air drying for five minutes permits evaporation of the carrier solvent, and a very thin, but fully effective film, will remain. Some customers have found that baking the applied film for 10 minutes at 90°C produces a more durable and abrasion resistant film and reduces the surface energy. The film does not cross-link like paint and is more akin to a thin layer of oil, even after baking out. For applications where low outgassing is a key property, baking the applied film for approximately 2 hours at 120°C is recommended to achieve optimum results.
Removing NYEBAR
Contamination of components with the barrier film would render them non-wettable by the lubricant, resulting in possible lack of lubrication and component failure. NYEBAR is readily dissolved by fluorinated solvents and to a lesser extent by chlorinated solvents. NYEBAR is relatively resistant to other commonly used solvents but prolonged immersion of the film should be avoided. Immersing NYEBAR treated components in effective solvents can dissolve the film and redeposit it in a vulnerable area and result in bearing failure. Mark all treated components to alert bearing users to the hazards of solvent immersion. It difficult to 100% completely remove the barrier film from a surface, so multiple rinse and wipe cycles are recommended, followed by surface wetting testing to make sure the surface is again wettable after cleaning.
