Conformal Coatings for Electronic AssembliesConformal coatings are essential for enhancing the reliability and long-term performance of electronic assemblies. They provide superior protection against:

  • Dust
  • Dirt
  • Abrasion
  • Fungus
  • Moisture
  • Chemicals
  • Mechanical stress
  • Shock and vibration

Properties of Conformal Coatings

Master Bond conformal coatings include very fast, one part UV curing formulations, one and two part epoxies, one and two part silicones and a unique cost effective latex system. Specific grades offer:

  • Low viscosity
  • Wide temperature resistance
  • Repairability
  • Rapid cures
  • High dielectric strength
  • Low stress

For intricate parts with shadowed out areas we also offer special “dual cure” coatings, which cure with both UV light and the addition of heat. Other special compounds are:

  • Optically clear
  • Non-yellowing
  • Cryogenically serviceable
  • Ultra low in viscosity

Environmentally friendly, Master Bond conformal coatings are 100% reactive and contain no solvents or diluents.
