Silicone resin potting glue is used for potting of electronic and electrical components, which can prevent moisture, dust, corrosion, and shock, and improve performance and stable parameters.

Features:

1. It is liquid before vulcanization, easy to infuse and easy to use
2. When potting, no low molecules are released, and there is no stress shrinkage.
3. It can be deepened without any corrosion.
4. It has repairability and good thermal cycling performance
5. Excellent resistance to high and low temperature, with a temperature range of -155℃--260℃
6. After vulcanization, the transparent silica gel becomes a transparent elastomer, which is clearly visible to the components encapsulated in the glue layer. You can use needles to measure the parameters of the components one by one, which is convenient for inspection and repair.

Classification:

1. Condensed silicone grease potting glue
2. Addition molding silicone resin potting glue

Like epoxy resin encapsulants, there are many types of silicone resin encapsulants. Generally it is two-component. According to different formulas, the ratio of the two components is also different. The curing conditions also vary according to the potting glue product. When evaluating and using potting glue, it is necessary to have a clear understanding of the performance of potting glue. If you use it for the first time, you might as well do a small batch trial production first.

How to choose potting products:

When choosing a potting product, you should choose the most suitable potting product based on the requirements of the electronic product itself, comprehensive evaluation of potting equipment, curing equipment, etc. In the evaluation, focus on the following characteristics of the potting compound:

Working temperature, hardness, viscosity, color mixing ratio
Curing conditions (room temperature curing, heating curing)
Performance requirements: thermal conductivity, insulation strength, flame retardant grade, environmental protection requirements, etc.

Key considerations for using potting glue:

1. Potting glue may produce precipitation during transportation and storage, please stir thoroughly before use. If the mixing is not uniform, it will greatly affect the performance of the potting compound. For the two-component potting glue, the glue of the two components should be pre-mixed to ensure that the compound within each component is evenly mixed.
2. Mix the two-component glue in full proportion (weight or volume)
3. If the requirements for potting are high, after the mixing and mixing are completed, the glue needs to be vacuumed to achieve seamless pouring
