3M™ Novec™ 2704 Electronic Grade Coating

3M™ Novec™ 2704 Electronic Grade Coating is designed for moisture and corrosion protection of printed circuit boards and electronic components. It is a low viscosity, low surface tension solution of a 4 wt% fluorochemical acrylic polymer carried in a hydrofluoroether solvent.

The coating dries to a thin, transparent, film with excellent hydrophobic and oleophobic properties. It repels oils, water, silicones and photoresist solutions. The coating is easy to apply (dip, spray or syringe dispensing), air-dries in seconds, requires little or no masking and is removable and repairable.

Features and Benefits

  • Easy application and processing – dries in seconds without the need for thermal post-curing
  • Requires little or no masking
  • Allows solder-through repairability and is easily removed for rework and repair
  • Contains a low level of volatile organic compounds (VOCs) and has low global warming potential
  • Is thermally and electrically stable with excellent dielectric properties
  • Provides excellent repellency, anti-wetting and anti-sticking properties against liquids, water, hydrocarbons, silicones, and photoresists
  • Contains a UV fluorescent dye incorporated into the polymer for improved QC inspection
