Product Details

3M Novec 2704 Electronic Grade Coating

3M™ Novec™ 2704 Electronic Grade Coating is a 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. A yellow-orange dye is incorporated into the fluorinated polymer backbone that will fluoresce under ultraviolet (UV) light, thus aiding inspection and detection in the quality control process.1 Novec 2704 coating is non-flammable, non ozone-depleting, low in toxicity, low in GWP, RoHS compliant and low in VOC.content.2

Dielectric breakdown: 3700 V/mil

Key Highlights

Key Features

  • Designed for moisture and corrosion protection of printed circuit boards and electronic components.
  • Low surface energy allows lubricating oils, silicones, etc. to bead and drain freely from coated surfaces.
  • Helps provide repellency and antiwetting properties against liquids –water, hydrocarbons, and silicones.
  • 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 contains a low level of volatile organic compound (VOC)2.

Application

  • Helps provide:
  • Moisture, chemical and corrosion protection for printed circuit circuit boards and their components.
  • Protection of display and touch panel components (e.g. anisotropic conductive film)
  • An easy and cost-effective alternative to conformal coatings.
  • Anti-wetting, anti-stiction, anti-migration and anti-corrosion properties in many diverse applications.
  • Can serve as:
  • Anti-migration coating for displays, spindle motors or lubricated electronic parts.
  • Anti-corrosion coating for a variety of materials and components.
