Henkel today announced that it has developed and introduced a new, advanced reflective coating for LED lighting applications with minimal material ageing to help LED luminaires maintain performance and extend their brightness lifetime. The new material, Stabilux, is a high-reflectance white coating that maximizes the usable light from surface-mounted or Chip-On-Board (COB) LED emitters.
Stabilux is a silicone-free formula designed to maintain high reflectance even after moving through harsh die attach and printed circuit board (PCB) assembly processes. In testing and in the field, Stabilux has been proven to retain up to 95% reflectance after undergoing three solder reflow cycles and after 2,000 hours of operation at 150°C. Stabilux is also UV- stable, displaying minimal performance degradation after prolonged exposure to LED light or sunlight.
As compared to liquid photoimageable (LPI) solder mask alone, Stabilux maintains its reflectance for a longer period of time. After solder reflow, solder mask reflectance often reduces to 80% or less, while Stabilux maintains nearly all of its initial reflectance following thermal processing. In addition, Stabilux is the only one-part, silicone-free, re-usable reflective coating on the market. After mixing, most two-part coatings are not re-usable, whereas the unused portion of Stabilux can be re-frozen for future use.
