3M™ Novec™ 1702 Electronic Grade Coating is a clear, low viscosity, low surface tension solution of a fluorochemical acrylic polymer carried in a hydrofluoroether solvent. A lower solids content version of Novec 1700 coating, it dries to an even thinner film and coats under low stand-off components. Designed for moisture and corrosion protection of printed circuit boards and electronic components, it dries to a thin, transparent, film with excellent hydrophobic and oleophobic properties
FEATURES
- Easy application and processing – dries in seconds without the need for thermal post-curing
- Requires little or no masking
- Allows solder-through repairability and is easily removed for rework & repair
- Contains no volatile organic compounds (VOCs) and has low global warming potential
- Is thermally and electrically stable with excellent dielectric properties
- Provides excellent repellency, anti-wetting and anti-sticking properties against liquids, water, hydrocarbons, silicones, and photoresists
APPLICATIONS
- Provides excellent moisture, chemical and corrosion protection to printed circuit boards and their components
- Is an easy and cost effective alternative to conformal coatings
- Can be used as a sacrificial surface treatment that can be selectively removed with Novec Engineered Fluids
