Light-cure conformal coatings cure tack-free in seconds upon exposure to UV/Visible or LED light and feature secondary heat or moisture-cure capability for shadow areas on PCBs. They protect printed circuit boards and components from extreme environmental conditions such as heat, chemicals, and humidity.

  • UV/Visible/LED light cure in seconds
  • Multi-Cure and Dual-Cure products (secondary heat or moisture cure)
  • High visibility fluorescence for inline Q.C.
  • One-part formulations, no solvents added
  • IPC and MIL SPEC approvals; some meet NASA ASTM E595 Low Outgassing
  • Flexible and rigid bonds to FPB and PCB substrates
  • Temperature/humidity resistance
  • Black coatings to hide sensitive circuitry

Environmental Benefits of Dymax® Light-Curable Materials N/A Dymax® understands that safe, ecologically friendly products benefit our customers, the environment, and us.
We have created materials that minimize ecological impact. These attributes include:
  • No solvents added materials
  • Halogen-free materials
  • REACH - no substance of very high concern (SVHC)
  • Eco-friendly, one-component materials
Dymax® Halogen-Free conformal coatings, encapsulants, and adhesives are documented by an independent laboratory to meet or exceed standards set forth in IEC 61249-2-21. This international directive defines halogen-free as < 900 ppm for chlorine, < 900 ppm for bromine and < 1,500 ppm total level of both combined. The current test method used for certification is BS EN 14582:2007.
