3M Novec 1904 Electronic Grade Coating is a fluorinated polymer diluted in a blend of 3M™ Novec™ 7100 and 7200 Engineered Fluids, segregated hydrofluoroether solvents, providing a low viscosity, low surface tension coating solution.
FEATURES
Designed for moisture and corrosion protection of printed circuit boards and electronic components
Low surface energy allows lubricating oils, silicones, photoresist solutions, etc. to bead and drain freely from coated surfaces
Helps provide repellency and anti-wetting 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 & water
Adheres to a variety of materials (metals, glass, ceramics, polymers, composites, laminates)
Thermally and electrically stable with good dielectric properties
Easy to apply – dries quickly without the need for post-application curing
Designed for spray application, however can also be applied via dip or syringe dispensing methods
APPLICATIONS
Moisture, chemical and corrosion protection for printed circuit boards and their components
Protection of display connections and components
An easy and cost-effective alternative to conformal coatings
Anti-wetting, anti-stiction, anti-migration and anti-corrosion properties in many diverse applications
