3M EGC-1700低表面能薄膜涂料
电子氟化液
3M Novec 低表面能薄膜涂料 EGC-1700上市与之配合使用的还有用于控制离子，金属和非挥发性残渣的 3M Novec HFE-7100DL 电子清洗液 3M Novec EGC-1700 可用于印刷线路板（PWBs）的保护涂层。使用后的PWBs表面留有一层非常薄的透明膜，起到极佳的防潮，防粘效果，对于各种低表面张力液体，诸如：油污、硅油、抗光蚀溶液等均有效。
3M Novec Electronic Coating EGC-1700 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-1700 dries to a thin transparent film with excellent anti-wetting, anti-stiction, anti-migration, and anti-corrosion properties required in many
diverse applications. This makes it applicable for many uses in the electronics industry including coating printed circuit boards, MR heads, micro motors, ball bearing tracks,MEMS, ink jet print cartridges and various components in hard disk drives. The low surface energy film repels liquids such as lubricating oils, silicones, and photoresist solutions used in the manufacturing of semiconductors.
Novec coating EGC-1700 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.
