LIGHT CAP® Conformal Coating for LEDs

LIGHT CAP® 9624 cures with UV light in seconds for rapid, room-temperature coating of LED arrays. The coating is a low VOC formulation that is solvent free as well as isocyanate free. The product features a low viscosity for thin coatings and requires no mixing or refrigeration. 9624 is heat resistant to 100° C and is also resistant to long-term UV exposure. Bondable substrates include leadframe, ceramic, PCB, as well as silicon.

LIGHT CAP® 9624 Applications Include:

  • Colorless encapsulation of COB LEDs
  • Instant forming of protective lenses for high-intensity LEDs
  • Conformal coating of LED arrays

LIGHT CAP materials contain no nonreactive solvents and cure upon exposure to light. Their ability to cure in seconds enables faster processing, greater output, and lower processing costs. When cured with Dymax UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. LIGHT CAP® 9624 is in full compliance with the RoHS2 Directives 2015/863/EU and 2011/65/EU.
