A brief introduction.

This product is a two-component, high light transmittance silicone fluid pouring sealant. Is mainly used in electronic seal, strengthen the integrity of the electronic devices and improve the resistance to external shock, vibration, improve the internal components and insulation between the lines, is helpful for device miniaturization, lightweight, avoid components, circuit directly exposed to the environment, improve the waterproof, moistureproof performance of device.

Characteristics of two.

1. High light transmittance, refractive index, high purity.

2. The weather is good, the flow performance is good, excellent electrical insulation properties and good sealing.

3. Good heat resistance, longer operating time.

4. This product points A and B component packaging, are colorless transparent liquid, avoid light environment can be long-term preservation.

5. High and low temperature resistance, can be in - 50 ℃ ~ 200 ℃ within the scope of use for a long time. After 300 ℃ after seven days of intensifying test colloid not crack, not hardened.

6. Colloid is colorless transparent elastomer after curing, the PPA, ABS and metal has the good adhesion.

Three typical applications

Suitable for automatic or manual dispensing production patch type high-power LED light-emitting diodes encapsulation phosphors, molding sealing glue, glue, potting of solar panels.

5. Use the method

1. According to the weight ratio of A: B = 1:1 proportion with glue, 10 minutes to stir to mix.

2. Vacuum deaeration 20 minutes.

3. Before injecting, please support under the 150 ℃ preheat 60 minutes or more moisture. As soon as possible before stent to damp sealing glue.

4. 110 ℃ first bake for 1 hour, then heat up to 150 ℃ 150 ℃ baking 3 hours or 2 hours, piecewise curing can effectively solve the problem of bubble increase yield.
