Dow Corning Greatly Expands LED Packaging Design Options With Launch of Three New Highly Reflective Silicone Coatings

Dow Corning, a global leader in silicones, silicon-based technology and innovation, significantly expanded the design flexibilities for LED packaging manufacturers today with the addition of three new highly reflective silicone coatings to its fast-growing portfolio of advanced LED solutions. Offering targeted solutions for cutting-edge LED designs – such as chip scale (CSP) and chip on-board (COB) packaging – the three new products also deliver versatile processing options ranging from conventional dispensing to emerging printing methods.

All introduced under the Dow Corning® brand label, the three new products include Dow Corning® WR-3001 Die Edge Coat, Dow Corning® WR-3100 Die Edge Coat and Dow Corning® WR-3120 Reflective Coating. In the future, products are planned to be added to match customer required processes.

"Manufacturers are aggressively seeking to design smaller, more efficient and cost-effective LED packages, which is driving demand for advanced new reflective materials that enable evolving application processes such as printing, and withstand increasingly stringent operating conditions," said Takuhiro Tsuchiya, Marketing Segment Leader, LED Packaging at Dow Corning. "These three cutting-edge coatings are only the first of a range of new products that we have in store for the industry. A proactive and collaborative innovator, Dow Corning formulated these three reflective silicone coatings specifically to help customers overcome today’s greatest design challenges and deliver highly reliable and differentiated products in the fiercely competitive LED market."

As with all Dow Corning® brand reflective materials, the three new grades maintain high reflectivity at low thicknesses and at sustained temperatures of 150°C – a temperature at which many organic coatings crack and yellow. Listed in order of increasing hardness, the three new products include:

  • Dow Corning  WR-3001 Die Edge Coat targets high-power CSP applications that demand LED materials with high thermal- and photostability. It is compatible with conventional dispensing processes.
  • Dow Corning  WR-3100 Die Edge Coat target CSP applications and other low- to middle-power LED package designs. Their relatively high hardness as Shore D 65 after cure makes them compatible with chip dicing processes.
  • Dow Corning  WR-3120 Reflective Coating also provides high thermal- and photostability suitable for high-power LED packaging applications, as well as the highest hardness of Dow Corning’s three new products. Suitable for printing processes, this advanced silicone further offers the highest reflectivity for enhanced LED performance.

A market leader in materials, expertise and collaborative innovation for LED lighting concepts, Dow Corning offers solutions that span the entire LED value chain, adding reliability and efficiency for sealing, protecting, adhering, cooling and shaping light across all lighting applications.
