Product Details

3M Novec 2708 Electronic Grade Coating

3M™ Novec™ 2708 Electronic Grade Coating is a single component fluorinated polymer diluted in 3M™ Novec™ 7200 Engineered Fluid, a segregated hydrofluoroether solvent, providing a low viscosity, low surface tension coating solution. 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 2708 coating is nonflammable, non-ozone-depleting, low in toxicity, low in GWP, RoHS compliant and is low VOC.* The coating contains a yelloworange 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: 2500 V/mil

Key Highlights

Key Features

  • Designed for moisture and corrosion protection of printed circuit boards and electronic components.
  • Is UV (ultra violet) light detectable for easy identification of coating and quality control.
  • 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 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 and contains less than 5% volatile organic components (VOCs)
