供应3M EGC-1704

3M? Novec? Electronic Coating EGC-1704 is a clear, low viscosity solution of a

fluorochemical acrylate polymer coating carried in a hydrofluoroether solvent. The solvent

is nonflammable, has low toxicity, contains no volatile organic compounds (VOCs), and

provides acceptable environmental properties for today’s demanding electronic applications.

When applied to clean, moisture-free surfaces such as copper, aluminum, ceramic, steel, tin

or glass, Novec coating EGC-1704 dries to form an ultra-thin transparent film with

excellent anti-wetting, anti-stiction, anti-migration, and anti-corrosion properties for many

diverse applications. The low surface energy film repels liquids such as lubricating oils,

hydrocarbon oils and silicones. 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.

Novec coating EGC-1704 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.
