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
