Transparent Silicone /
Epoxy Material for LED device
Shin-Etsu Chemical Limpid Si® series is a silicone resin for encapsulation materials, sealing materials for various LEDs (white LED, ultraviolet LED, blue LED). LED devices with less deterioration can be produced by utilizing the characteristics of silicone such as long-term durability, high temperature stability, high adhesion and high refractive index even at high temperature operation due to high brightness of LED.
Coating LED chip used for source of white light, it can be used mix it with phosphor. It is also possible to supply products in film type mixed with phosphor.
Shin-Etsu offers a wide range of products from soft gels to hard types applicable for transfer molding system, and can supply grade suitable for your needs.
