3M Novec 1700 EGC-1700 Electronic Grade Coating Clear Fluoropolymer PCB Moisture Corrosion Protection

3M Novec 1700 Electronic Grade Coating (EGC-1700)

The 3M Novec 1700 is a clear, ultra-thin fluoropolymer conformal coating engineered for the protection of sensitive electronic assemblies. Applied as a dilute solution in a hydrofluoroether (HFE) carrier solvent, it deposits a transparent, hydrophobic film that shields PCBs and components from moisture, corrosion, and contamination — without masking, rework, or lengthy cure cycles.

Key Features

• Clear Fluoropolymer Film: Deposits an ultra-thin, optically transparent protective layer
• Hydrophobic & Oleophobic: Repels water, oils, and flux residues to prevent corrosion and leakage currents
• Electronic Grade (EGC): Formulated for direct use on populated PCBs and sensitive components
• Fast Drying: HFE carrier solvent evaporates rapidly at room temperature — no oven cure required
• Non-Flammable Carrier: Novec HFE solvent is non-flammable, improving workplace safety
• No Masking Required: Coating is easily removed from connectors and contacts with standard solvents
• Low Global Warming Potential: Environmentally preferable alternative to traditional fluoropolymer coatings

Typical Applications

• PCB conformal coating for moisture and corrosion protection
• Consumer and industrial electronics assemblies
• Automotive electronics and sensors
• Aerospace and defense avionics
• LED modules and lighting assemblies
• Medical device electronics
