3M™ Novec™ 2702
4 5 (1 evaluate)Category: 3M™
3M™ Novec™ 2702 Electronic Grade Coating is a clear, low viscosity, low surface tension solution of a fluorochemical polymer coating carried in a hydrofluoroether solvent. Designed for moisture and corrosion protection of printed circuit boards and electronic components, it dries to a thin, transparent, permanent film with excellent hydrophobic and oleophobic properties. Easy to apply, the coating should be post-cured to provide added durability and abrasion resistance. It is non-flammable, low in toxicity, non-ozone depleting and RoHS compliant.

Features of 3M™ Novec™ 2702 Electronic Grade Coating
• Low surface tension of the coating solution provides increased surface wetting, especially under low profile components
• Cross-links with a thermal cure for durable protection
• Contains no volatile organic compounds (VOCs) and has low global warming potential
• Can be applied to metals, glass or epoxy laminates
• Provides excellent repellency, anti-wetting and anti-sticking properties against liquids – water, hydrocarbons, silicones, and photoresists
• Is insoluble in solvents such as heptane, toluene and water
• Is thermally and electrically stable with excellent dielectric properties
• Covalently bonds to glass and metal oxide layers
• The polymer can endure up to 200°C for prolonged periods and maintain good repellency
• Has low surface energy which allows lubricating oils, silicones, etc. to bead and drain freely coated surfaces
Applications of 3M™ Novec™ 2702 Electronic Grade Coating
• 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 durable hydrophobic or oleophobic surface treatment in many diverse applications
• Can serve as
– an anti-stiction coating for liquid crystal displays, micromotors or MEMS (Micro Electronic Mechanical Systems) components
– an anti-migration coating for displays, spindle motors or lubricated electronic parts or
– an anti-corrosion coating for a variety of materials and components
