3M™ Novec™ 2704
- Ultra-thin hydrophobic & oleophobic coating with UV tracer
- Dipping & spray process
- Easy & fast process
3M™ Novec™ 2704 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 2704 coating is non-flammable, non-ozone-depleting, low in toxicity, low in GWP, RoHS compliant and is low VOC.* The coating contains a yellow-orange 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.
