3M Novec 2702 Electronic Grade Coating

3M™ Novec™ 2702 Electronic Grade Coating is a clear, low viscosity, low surface tension solution of a fluorochemical polymer coating carried in a hydrofluoroether solvent. Designed for moisture and corrosion protection of printed circuit boards and electronic components, it dries to a thin, transparent, permanent film with excellent hydrophobic and oleophobic properties. Easy to apply, the coating should be post-cured to provide added durability and abrasion resistance. It is non-flammable, low in toxicity, non-ozone depleting and RoHS compliant.

Dielectric breakdown: 1500 V/mil (20°C, 30%RH

Key Highlights

Key Features

  • Low surface tension of the coating solution provides increased surface wetting, especially under low profile components.
  • Cross-links with a thermal cure for durable protection.
  • Contains no volatile organic compounds (VOCs) and has low global warming potential.
  • Can be applied to metals, glass or epoxy laminates.
  • Provides excellent repellency, anti-wetting and anti-sticking properties against liquids – water, hydrocarbons, silicones, and photoresists.
  • Is insoluble in solvents such as heptane, toluene and water.
  • Is thermally and electrically stable with excellent dielectric properties.
  • Covalently bonds to glass and metal oxide layers.
  • The polymer can endure up to 200°C for prolonged periods and maintain good repellency.
  • Has low surface energy which allows lubricating oils, silicones, etc. to bead and drain freely from coated surfaces.


  • Provides excellent moisture, chemical and corrosion protection to printed circuit boards and their components.
  • Is an easy and cost effective alternative to conformal coatings.
  • Can be used as a durable hydrophobic or oleophobic surface treatment in many diverse applications.
  • Can serve as – an anti-stiction coating for liquid crystal displays, micromotors or MEMS (Micro Electronic Mechanical Systems) components – an anti-migration coating for displays, spindle motors or lubricated electronic parts or – an anti-corrosion coating for a variety of materials and components.
