Recommended whenever electrical corrosion and reliability or lubricant migration are a potential problem, NyeBar® fluorocarbon barrier films control oil creep and prevent corrosion. Non-wettable with low surface tension, they act as a dam around the lubricated area to prevent oil migration and subsequent contamination of nearby, sensitive components.
For example, small amounts of oil or grease may be used to lubricate rolling element bearings in a small electric motor in an automotive application. A thin coating of NyeBar® around the shaft, where it exits the bearing, prevents migration of the lubricant, which otherwise may foul nearby electrical contacts.
In addition to controlling oil creep, a thin coating of NyeBar® is also used to protect printed circuit boards by repelling moisture, oil and attendant dust entrapment.
Applied by dipping, spraying, or brushing, NyeBar® can be used to coat a variety of materials including copper, aluminum, steel, tin, plastic, and glass. It can be formulated to match desired rates of evaporation, to meet ultraclean electronics and aerospace requirements, and with an added UV tracer, to facilitate quality inspection.
