LED environments are becoming more
demanding, inside and out.
Within LED packages, temperatures are
rising as the market calls for higher light output from more compact designs.
Meanwhile, LED lighting is penetrating more outdoor applications, where
sensitive components require superior protection against ingress of
moisture and dust. The convergence of these trends has challenged conventional
LED encapsulants, which can perform less reliably when exposed to thermal
In contrast, silicone coatings, encapsulants
from Dow Corning offer the right balance of thermal stability and powerful
adhesion to form strong, flexible, durable seals that protect high-brightness
LEDs from environmental contamination. Our silicone coatings seal and protect
LED solder joints to circuit boards, while our silicone adhesives and
encapsulants offer protection much higher on the legs of the LED
Available in a variety of viscosities and
cure chemistries, Dow Corning's high-performance silicones deliver
excellent unprimed adhesion to a variety of common substrates including
ceramics, reactive materials and filled plastics. This ensures excellent
physical protection across the entire spectrum of LED applications, from chip level
materials to outdoor lamps and
luminaires operating at temperatures from -45°C to 200°C.
In addition, optical
silicones from Dow Corning expand options for LED designs that require
encapsulants to double as lensing elements. These optical-quality materials
deliver refractive indexes upwards of 1.5, and will not delaminate, crack or
yellow at temperatures exceeding 150°C. In addition to optimizing optical
efficiency, these materials enable a strong, thermally stable seal that can
extend the overall quality and lifetime of advanced LED designs.
