Introduction
3M™ Novec™ 2704 Electronic Grade Coating is a fluorinated polymer solution carried in a hydrofluoroether solvent. Designed for moisture and corrosion protection of printed circuit boards and electronic components, the polymer coating dries to a thin, transparent film with excellent hydrophobic and oleophobic properties. It does not need curing and is easy to apply, remove and repair. Both the solution and polymer are low in toxicity, non-ozone depleting and RoHS compliant. The coating contains a yellow-orange dye that is designed to fluoresce under UV light to aid the inspection of the coating and quality control of the coating process.

Can be dipped, sprayed or lectively deposited. Surfaces to be coated should be clean and dry before application. Masking may not be required for many larger connector types but testing is always suggested. The solvent will evaporate quickly and the fluorochemical polymer film will dry in minutes.Application Options Dipping (preferred), spray or syringe dispen Dilution Can be diluted with 3M ™ Novec ™ 7200 Engineered Fluid Drying/Curing Dries at room temperature; can be handled in under two minutes Removability Removable with a variety of 3M Novec Engineered Fluids Safety, Handling, Storage, Shelf Life To avoid thermal decomposition, the coating solution should not be heated above 150°C (302°F) and the dried fluorochemical polymer film should not be
heated to temperatures above 250°C (482°F). When stored under conditions of 16-27°C (60-80°F) and less than 60% R.H. in the original, unopened container, the shelf life is certified for 1 year from the date of manufacture. Before using this product, plea read the current product Material Safety Data Sheet (available through your 3M sales or technical rvice reprentative or at /Novec) and the precautionary statement on the product package. Follow all applicable precautions and directions. Always practice smart and safe industrial hygiene practices.
Coating Inspection
This polymer contains a visible (yellow/orange) and UV fluorescent dye to aid in the identification and quality control of the coating process. The dye is reacted into the backbone of the polymer. It will not migrate or off-gas from the polymer film. Inspection of the polymer under a range of UV frequencies can be accomplished with commercially available UV lamps designed for industrial u. The dye fluoresces brightest under higher frequency UV (254 nm) but will also fluoresce at other common UV frequencies (i.e. 310, 365 nm). Plea follow the UV lamp manufacturer’s recommendations on safe handling of UV radiation. Fluorescence of the polymer will depend on veral factors including coating thickness; substrate type and color; UV source frequency, intensity and distance from the coating surface.
