Adhesives Satisfy Stringent Criteria for Use with LEDs
Adhesive products from Henkel Corp. are now being used by Cree, Inc. in its LED lighting products. Henkel is the first adhesives manufacturer to demonstrate the ability of its products to meet a stringent chemical testing protocol developed by Cree for use in its high performance LED lighting components. Henkel collaborated with Cree to identify, test, and validate a wide range of Loctite® adhesives to determine their performance in direct and indirect LED assembly applications.
Cree reviewed and verified the results of the tests conducted by Henkel and confirmed that numerous Loctite® adhesives, sealants, potting materials, and threadlockers satisfy the stringent chemical compatibility testing protocol identified in the Cree® LED Solution Provider Program for use with its LED lighting components.

Ensuring Quality Consistency, Reliability
"Adhesives and sealants are important to the production of an LED lighting fixture," explains David Cox, director of Alliance Development at Cree. "Incompatible materials such as adhesives can cause the encapsulant to turn brown and block light emitted from the LED. We are excited by Henkel's development of Loctite® products that meet our requirements and help to maintain the color point of our LEDs. Such adhesives help customers to ensure the consistent quality and long-term reliability of our LED lighting components."
Henkel adhesive technologies help to ensure a long life for LED lighting devices, even in applications exposed to harsh conditions, such as extreme temperatures, dust, dirt, vibration, and underwater submersion. Henkel LED adhesive products are engineered for use in LED lighting devices found in roadway/parking lot, industrial/commercial, consumer/residential, and architectural applications.
