In order to improve the reliability and stability of electronic components, people usually pour a layer of electronic potting adhesive inside them, because the electronic potting adhesive has certain electrical insulation and thermal conductivity. After potting, it can effectively improve the insulation capacity between internal components and lines, and also play a certain role in heat dissipation, It can effectively ensure the stability of electronic components.

There are mainly two kinds of potting adhesives commonly used on electronic components: silicone potting adhesive and epoxy potting adhesive. The potting adhesives of the two materials are used in different occasions according to their own advantages and disadvantages. Therefore, our company has sorted out the advantages and disadvantages of silicone potting adhesive and epoxy potting adhesive for your reference. I hope you can choose the potting adhesive suitable for your own products.

1. The potting adhesive made of epoxy resin has good modification ability, and its thermal conductivity can be adjusted freely according to different potting products. It also has excellent electrical insulation ability. However, it has poor resistance to cold and heat changes, and it is prone to small cracks in the process of cold and heat alternation, which affects the moisture-proof ability of electronic components; The hardness of the solidified colloid is also very high, which is easy to strain electronic components. If the hardness is too high, it is difficult to have a good impact resistance. It is generally used in electronic components that do not have much requirements for environmental mechanics. Such as capacitors, mutual inductors, electronic transformers and other electronic components.

2. Silicone potting adhesive has better modification ability and electrical insulation ability than epoxy resin, and has excellent cold and heat shock resistance. It can withstand cold and heat shock of - 60 ℃ ~ 200 ℃, does not crack, maintains elasticity, and improves the moisture-proof performance of electronic components. Because it is an elastomer after curing, it is potted in electronic components, It can also play a good impact resistance, and has excellent resistance to outdoor ultraviolet and atmospheric aging. It can be widely used for electronic components working in various harsh environments. Such as outdoor transformer, ignition coil with high temperature resistance requirements and electronic equipment in coastal areas.
