Protective Coatings for Printed Circuit Boards


Easy to apply, nonflammable surface modifiers - alternatives to conformal coatings

Consumer demand for electronic devices that are more compact, portable and loaded with features has made protecting sensitive electronic components against soils, contaminants and moisture more challenging than ever before.

Now, 3M brings you a family of fast drying, easy-to-apply, protective electronic coatings for printed circuit boards and other electronic components – all designed to maintain optimal performance and reliability in a broad range of environments and applications.

3M™ Novec™ Electronic Grade Coatings provide

  • Excellent protection and repellency properties
  • Improved manufacturing efficiencies
  • Health and safety benefits
  • Environmental and sustainability benefits

These nonflammable surface modifiers offer you a reliable alternative to traditional conformal coatings – combining outstanding performance with easy application.

Features and Benefits

  • Excellent repellency – reduces the component surface energy, repelling moisture and many liquids
  • Protects - thermally and electrically stable, with excellent dielectric properties
  • Thin - provides protection by drying to a one micron thick, clear, uniform protective film
  • Speed of application - air-dries in seconds, minimizes masking, thermally cures quickly
  • Ease of application - can be applied via dip, spray*, brush or syringe dispensing
  • Sustainable – made with sustainable chemistries, they are non ozone-depleting, contain no volatile organic components and have low global warming potential
  • Health and safety – are nonflammable and low in toxicity

  • *Use of appropriate PPE or engineering controls recommended.
