3M™ Novec™ 2704 Electronic Grade Coating

3M™ Novec™ 2704 Electronic Grade Coating is designed for the protection of printed circuit boards and electronic components. It is a clear, low viscosity solution of a 4 wt% fluoropolymer carried in a hydrofluoroether solvent. It is UV detectable. Novec 2704 coating is non-flammable, non ozone-depleting, low in toxicity and low in GWP.

"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."

• 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 & repair
• Low Global Warming Potential (GWP)
• 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
