3M Novec 1702 Electronic Grade Coating

3M™ Novec™ 1702 Electronic Grade Coating is a single component fluorinated polymer diluted in 3M™ Novec™ 7100DL Engineered Fluid, a segregated hydrofluoroether solvent, providing a low viscosity, low surface tension coating solution. A lower solids content version of 3M™ Novec™ 1700 coating, it dries to an even thinner film and coats under low stand-off components. Designed for moisture and corrosion protection of printed circuit boards and electronic components, it dries to an ultrathin, transparent coating with excellent hydrophobic and oleophobic properties. It does not need curing and is easy to apply. Novec 1702 coating is nonflammable, non-ozone-depleting, low in toxicity, low in GWP, RoHS compliant and VOC exempt (per the U.S. EPA).

Key Highlights

Key Features

  • Designed for moisture and corrosion protection of printed circuit boards and electronic components.
  • Low surface energy allows lubricating oils, silicones, photoresist solutions, etc. to bead and drain freely from coated surfaces.
  • Helps provide repellency and antiwetting properties against liquids – water, hydrocarbons, silicones and photoresists.
  • Helps protect against corrosive gases and vapors in addition to liquids.
  • The polymer can endure up to 175°C (347°F) for 24 hours and maintain repellency.
  • Essentially insoluble in solvents such as heptanes, toluene and water.
  • Adheres to a variety of materials (metals, glass, ceramics, polymers, composites, laminates)
  • Thermally and electrically stable with good dielectric properties.
  • Easy to apply – dries quickly without the need for post-application curing.
  • Excellent surface wetting, especially under low standoff SMT components.
  • Allows solder-through repairability.
  • Non-flammable, non-ozone-depleting, and low in toxicity.
  • Low in global warming potential (GWP), RoHS compliant and volatile organic compound (VOC) exempt (per the U.S. EPA)


  • 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.
