Lock Out Dust and Moisture, Lock in Reliability and Greater Protection
LED Environments are Becoming More Demanding, Inside and Out.
Within LED devices, 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 PCB devices demand 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 extremes.
In contrast, silicone coatings, potting/encapsulants and adhesives/sealants from Dow Consumer Solutions offer the right balance of thermal stability and powerful adhesion to form strong, flexible, durable seals that protect high-brightness LED assemblies from environmental contamination.
Available in a variety of viscosities and cure chemistries, Dow Consumer Solutions' 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.
A specialty class of encapsulants are the optical silicones from Dow Consumer Solutions that 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.
More than a world-class materials supplier, Dow Consumer Solutions is an expert and dedicated collaborator. If our Product Finder cannot identify an off-the shelf solution that meets your precise specifications, our expert application engineers will work with you to understand your application and identify how to best solve your needs.
