RAY-8626 silicone gel/resin for LED light encapsulation use

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，RAY-8626 is high heat resistant additional type silicone rubber

A new product Silicone rubber ,which had heat and weather resistant ,could be apply on electric circles and LEDs used.

Operation process :

weight : Take RAY-8626A and RAY-8626B by 10:1

(weight ratio).

  Defoaming  : place the mixture in vacuum vessel，kept vacuum lower than 500 mg Hg.

  Filler :       Be careful pouring silicone to the container, avoid

               occur bubble

  Harden  :    Preheating(60℃X 15 min then 80℃X 30 min). then Curing 150℃X 40 min. 

RAY- 8626為加成型矽凝膠，硬化後具有良好的物性,手感及緩衝性，可用於印刷電路板及LED蕊片及螢光粉之固定保護,絕緣,防潮及緩衝處理。

絕緣強度                   > 20 Kv/mm

折射率                       1.407

穿透率(1mm)              95% /全光譜

秤重   取RAY-8626A與RAY-8626B以1:1（重量比）之比例充份混合（此混合物粘度約3500 cps）

去泡   將此混合物，置入真空設備中，真空度約在500 mmHg（小心氣泡溢出容器外），直到氣泡被完全抽出

灌模   小心地將混合物灌入欲成模之模具中，過程中注意避免產生氣泡

硬化   已灌入矽膠的模具，置入80℃烘箱中30鐘可在模具中成型
