Dow Corning's New Silicone Technology Brings Innovation to LED

Dow Corning has further expanded its industry-leading phenylsilicone optical potting product line and introduced five new two-component, heat-curing products. The reliability of new products has been further improved, with better silver electrode anti-corrosion capabilities and better durability for increasingly stringent LED product design standards. They also further validated Dow Corning's commitment to continuous improvement in the performance and reliability of solid-state lighting.

Dow Corning® OE-6662 and OE-6652 Optical Encapsulants are better at resisting silver corrosion with Shore D64 and D59 hardness ratings. The two products have better gas barrier function, which can protect delicate silver-plated LED electrodes from sulfur. In addition to reducing luminous efficiency losses, this feature also extends the overall quality and service life of advanced LEDs.

The new OE-7620, OE-7630, and OE-7640 optical sealants have Shore D26, D29, and D43 hardness ratings, respectively. These slightly lower hardness materials provide better mechanical performance protection for evolving LED package designs. In addition, these three new grades of products can significantly improve thermal stability and light stability compared to existing products, ensuring the optical quality stability of LED light sources over their lifetime.

“The requirements for the design and application of next-generation LED light sources are increasing. Global LED light source manufacturers are looking for innovative new material solutions to withstand the higher internal temperatures of new LED products, as well as more rigorous work. Environment,” commented Kaz Maruyama, Global Industry Director, Dow Corning Lighting Solutions. “The new Dow Corning Silicone Optic Encapsulants further enrich our comprehensive product line, providing advanced lighting design with the necessary performance and protection to ensure that Reliable and high-quality lighting effects over the lifetime."

The newly released Dow Corning high-purity silicone optical adhesive has been sold worldwide and is suitable for conventional dispensing and molding processes.

Dow Corning Corporation is a global innovation company dedicated to providing high-performance silicone materials for the lighting industry of the future. Its solutions can benefit the entire value chain and increase reliability for sealing, protection, adhesion, cooling, and light control in lighting applications. efficacy.
