Additional type two component Silicone Rubber/Gel for LED ,IC Encapsulating / Packageing use
Code No. RAY-8636 in 1: 1 ratio
Introductions :
Due to the energy saver, best brightness and higher powder LEDs was applied on very field,as general illumination backlight for LCD, and Automotive light. In encapsulation epoxy resin can not stand heat cycle on applications?A new product Silicone rubber ,which had heat and weather resistant ,could be apply on electric circles and LEDs used.
