In order to improve the reliability of electronic components and the use of stability, in its internal perfusion is often a layer of electronic potting glue, because electronic potting glue have ability to electrical insulation and thermal conductivity, potting after can effectively improve the internal components and circuit between the insulating ability, also played a cooling effect, can effectively guarantee the use of electronic components.

The potting glue commonly used in electronic components mainly has two kinds of materials, respectively: epoxy resin material and silicone material, two kinds of material potting glue according to their own advantages and disadvantages, the application of the occasion is not the same. Such as: material potting glue, epoxy resin itself has good capability of modification, according to the different of potting products adjust the coefficient of thermal conductivity of itself also has excellent electrical insulation, but poor ability to resist cold, in the process of cold and hot alternative easily appear tiny cracks, which affects the electronic moistureproof ability; The hardness of the solidified colloid is also very high, it is easy to pull the electronic components, the hardness is too high also difficult to play a good impact resistance, generally used in the environmental mechanics of the electronic components without too much requirements. Such as: capacitors, transformers and electronic transformers and other electronic components.

And organic silicon material potting glue has not only better than the epoxy resin modified and electrical insulating ability, ability to resist cold and hot shock is also quite good, can afford to - 60 ℃ ~ 200 ℃ cold and hot shock, no crack, and keep elasticity, improve the moisture-proof performance of electronic components, because after curing for elastomer, so potting in electronic components, Can also play a good impact resistance, resistance to outdoor ultraviolet light and atmospheric aging performance is also very excellent. Can be widely used in a variety of harsh environment working electronic components. Such as outdoor transformers, ignition coils with high temperature requirements and electronic equipment in coastal areas.

To sum up, the silicone potting adhesive is superior to the epoxy resin potting adhesive in performance, so in pursuit of better protective effect, the first choice should be silicone potting adhesive.
