3M Novec 1702 Electronic Grade Coating Ultrathin Low Standoff Protection
Type: Electronic Grade Fluoropolymer
Solids: 0.2 wt%
Coating Thickness: <100 nm
VOC Status: Exempt
Packing: 5KG / 20KG drum
3M Novec 1702 Electronic Grade Coating is a low solids version of Novec 1700, designed specifically for applications requiring an even thinner protective film. This clear, low-viscosity solution of a fluorinated acrylic polymer in hydrofluoroether solvent dries to a transparent film less than 100 nanometers thick — ideal for coating under low stand-off components where clearance is limited. It provides excellent moisture and corrosion protection for printed circuit boards and electronic components with outstanding hydrophobic and oleophobic properties.
Novec 1702 offers all the advantages of Novec 1700 with an even lower profile. It requires no curing, dries at room temperature in seconds, and can be handled in under two minutes. The coating provides excellent repellency against water, hydrocarbons, silicones, and photoresists, with water contact angle of 105° and hexadecane angle of 65°. It is easily removable for rework using Novec 7100DL Engineered Fluid and allows solder-through repairability. Environmentally, it is nonflammable, non-ozone-depleting, low in toxicity, low GWP, RoHS compliant, and VOC exempt (per U.S. EPA). With a 4-year shelf life and compatibility with metals, glass, and epoxy laminates, Novec 1702 is a versatile, cost-effective alternative to traditional conformal coatings.

Core Advantages of 3M Novec 1702 Electronic Grade Coating
- Ultrathin coating: <100 nm — ideal for low stand-off components and tight clearance applications
- Low solids formulation: 0.2 wt% — even thinner than Novec 1700 for maximum clearance
- Hydrophobic and oleophobic — water contact angle 105°, hexadecane angle 65°
- No curing required — dries at room temperature in seconds, handle in under two minutes
- Solder-through repairability — components can be reworked without removing the coating
- Removable for rework — easily removed with Novec 7100DL Engineered Fluid
- VOC exempt (U.S. EPA) — environmentally compliant for electronics manufacturing
- Low GWP and zero ODP — sustainable alternative to traditional coatings
Main Applications
- PCB moisture and corrosion protection — for consumer, industrial, and automotive electronics
- Low stand-off component coating — coats under low-profile SMT components where clearance is limited
- Anti-migration coating — prevents migration of lubricants and photoresists in displays and spindle motors
- Anti-stiction coating — for MEMS, micromotors, and liquid crystal displays
- Sacrificial surface treatment — selectively removable with Novec engineered fluids for rework
