3M? Novec? Electronic Coating EGC-1702 is a clear, low viscosity solution of a fluorochemical acrylate polymer coating carried in a hydrofluoroether solvent. The solvent is nonflammable, has low toxicity and provides acceptable environmental properties for today’s demanding electronic applications. It contains no volatile organic compounds (VOCs). When applied to clean, moisture-free surfaces such as copper, aluminum, ceramic, steel, tin or glass, Novec coating EGC-1702 dries to form an ultra-thin transparent film with excellent anti-wetting, anti-stiction, anti-migration, and anti-corrosion properties for many diverse applications. This makes it ideal for many uses in the electronics industry including coating MR recording heads, spindle motors, head gimbal assemblies (HGAs), MEMS, CRTs and LCDs. The low surface energy film repels liquids such as lubricating oils, hydrocarbon oils and silicones. Novec coating EGC-1702 will form a clear, nearly invisible, uniform film that is insoluble in solvents such as heptane, toluene, and water. It is strippable with fluorinated solvents. These films can endure up to 175°C for prolonged periods and maintain good repellency
