UV3108-M – UV/moisture cure Conformal Coating

UV3108-M is a UV/moisture dual-curing UV protective glue prepared from special materials. When used, it has good process performance, excellent flowability and tiling properties, and can be quickly cured to form a film with good strength, high hardness, waterproof and corrosion resistance. It is often used in the fields of covering and protecting PCB circuit boards and electronic components.

Features and benefits

  • PCB circuit board approval protection
  • Approval protection of electronic components
  • High transparency, low viscosity, and good process performance
  • Fast curing, high hardness, excellent bonding performance
