3M Novec 1908 Electronic Grade Coating Highest Solids PCB Protection
Type: Electronic Grade Fluoropolymer
Solids: 8.0 wt%
Thickness: 0.4-5.0 µm
Dielectric Strength: 3700 V/mil
Packing: 5KG / 20KG drum
3M Novec 1908 Electronic Grade Coating is the highest solids version (8.0 wt%) in the Novec coating product line, delivering the thickest protective film (0.4-5.0 microns) for maximum moisture and corrosion protection of printed circuit boards and electronic components. This clear, low-viscosity fluorinated polymer solution is diluted in a blend of 3M Novec 7100 and 7200 Engineered Fluids, providing excellent surface wetting and uniform coating coverage. With the highest viscosity (2.24 cP) and solids content among Novec coatings, Novec 1908 offers the most robust protection for demanding electronics applications.
Novec 1908 provides superior dielectric performance with a dielectric breakdown strength of 3700 V/mil and a low dielectric constant of 2.8. Its glass transition temperature of 52°C ensures excellent thermal stability. The coating delivers outstanding hydrophobic and oleophobic properties with water contact angle of 105° and hexadecane angle of 65°, repelling water, hydrocarbons, silicones, and photoresists effectively. It adheres well to metals, glass, ceramics, polymers, and laminates, and withstands 175°C for 24 hours while maintaining repellency. Environmentally, it is nonflammable, non-ozone-depleting, low in toxicity, low GWP, RoHS compliant, and VOC exempt (per U.S. EPA). With a 2-year shelf life and easy application by spray, dip, or syringe dispensing, Novec 1908 is the ultimate choice for high-reliability PCB protection and conformal coating applications.
