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.
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)
