3M Novec 27002 Electronic Grade Coating

3Mâ„¢ Novecâ„¢ 27002 Electronic Grade Coating is a fluorinated polymer solution carried in a hydrofluoroether solvent. Designed for moisture and corrosion protection of printed circuit boards and electronic components, the polymer coating dries to a thin, transparent film with excellent hydrophobic and oleophobic properties. It does not need curing and is easy to apply, remove and repair. Both the solution and polymer are low in toxicity, non-ozone depleting and RoHS compliant.

Dielectric breakdown: 3700 V/mil

Thermal conductivity: 0.1 W/m*K

Key Highlights

Key Features

  • Easy application and processing – dries in seconds without the need for postapplication curing.
  • Can be easily removed for rework and repair using 3M™ Novec™ Engineered Fluids.
  • Allows solder-through repairability.
  • Contains less than 1% volatile organic compounds (VOCs) and has low global warming potential.
  • Is thermally and electrically stable with good dielectric properties.
  • Adheres to a variety of materials (metals,
  • glass, ceramics, polymers, composites,
  • laminates)
  • Provides excellent repellency, antiwetting and anti-sticking properties against liquids – water, hydrocarbons, silicones, and photoresists.
  • Is insoluble in solvents such as heptanes toluene and water.
  • The polymer can endure up to 175°C for 24 hours and maintain repellency.
  • Has low surface energy which allows lubricating oils, silicones, photoresist solutions, etc. to bead and drain freely from coated surfaces.
  • Has excellent surface wetting, especially under low standoff SMT components.


  • Moisture, chemical and corrosion protection for printed circuit boards and their components.
  • An easy and cost-effective alternative to conformal coatings.
  • Anti-wetting, anti-stiction, anti-migration and anti-corrosion properties in many diverse applications.
  • Anti-migration coating for displays, spindle motors or lubricated electronic parts.
  • Anti-corrosion coating for a variety of materials and components.
