Surface Mount Adhesive for LED encapsulant

Introduction

Liquid silicone potting adhesive with 2 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.

e.

Feature

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

Application

LED encapsulant,strip of high-power LED ,Encapsulation of solar panels

How to use

1. Use ratio BQ-4371A 1 copy

BQ-4371B 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.

5. Curing condition

150°C/0.5h(for short roast)+150°C/3h(for long roast)

storage

Sealed storage in cool and dry conditions at room temperature.

Shelf life

6 months under above conditions. It remain can be used after shelf life if the technical data is qualified.

Package

Part A:0.5 Kg/bottle,Part B:0.5 Kg/bottle

Notes

Application

During the application or storage period ,avoid contact the subjects which contain the P, S, N, Sn, water, polyurethane resin and so on .or cause the obstruction and deterioration of curing.(e.g.solution for cleaning the plastic cups, additional toxic components within the oven, organic acids,etc.)

Safe

1. Note the labor wearable during the application, avoid high temperature burns during the construction process, and prohibit consumption.

2. Use the product carefully, note the safety issues before and during use, more over, follow the relevant provisions of national or local government safety regulations. (Refer to the appropriate safety guidelines for details in MSDS)
