High purity silicone potting sealant for LED

Introduction 

Liquid silicone potting adhesive with two-component and ordinary refractive index. Mainly used for sealing of electronic components, so as to strengthen the integrity of electronic components, improve the resistance against external shocks and vibration; enhance the insulation of internal components and lines, it’s helpful for the device become smaller and lighter, avoid the devices and lines exposed to the environment directly. Improve the performance of the waterproof and moisture resistant. 

Feature 

High transmittance; Flow performance; Heat resistance; Good weather resistance; High adhesive with PPA

Application

How to use 

1. Use ratio

   BQ-4365A    1 copy

2. Mix two parts evenly(mixing time recommended--8 min), and then defoaming it under vacuum for 2-3min(it’s unnecessary to heat in the whole process)

3.After defoaming, potting it by needles or dispensing. In order to drive the air out of rubber completely, you’d better defoaming again under vacuum to the needles which has full of the rubber. 

4. Before encapsulation, preheat the stand or base 120°C/3h at least at the same time, so that the wet gas can be cleared up and avoid the bubble when curing.
