3M Novec 2701 Electronic Grade Coating

3Mâ„¢ Novecâ„¢ 2701 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. The coating contains a yellow-orange dye that is built into the polymer and designed to fluoresce under UV light to aid the inspection of the coating and quality control of the coating process.

Dielectric breakdown: 3700 V/mil

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.
  • Is UV detectable for easy identification of coating and quality control.
  • 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.
  • Protects against corrosive gases and vapors in addition to liquids.

Applications

  • Provides excellent moisture, chemical and corrosion protection to printed circuit boards and their components.
  • Provides protection of display and touch panel components.
  • Is an easy and cost-effective alternative to conformal coatings.
  • Provides excellent anti-wetting, anti-stiction, anti-migration and anti-corrosion properties in many diverse applications.
  • Can serve as an anti-corrosion coating for a variety of materials and components.
