In 2023, well-known electronic potting material manufacturers include Dow Corning, Youxing Shark, Huitian New Materials, and Sibao Technology’s Beginor Polymer. Electronic potting material is a type of adhesive used to seal electronic components, preventing them from being directly exposed to air, preventing them from being corroded by the environment, improving their service life, and achieving waterproof, dustproof, and thermal conductivity. There are usually three types of materials for electronic potting adhesive: epoxy resin, organic silicon, and polyurethane. The electronic potting adhesive used on different components will also be different. So, how should we choose a suitable brand of potting adhesive for our products when facing so many types of potting material?
When choosing electronic potting adhesive, we must pay attention to the following points:
1、Electrical and insulation performance (organic silicon is the best, followed by polyurethane, and epoxy resin is the worst)；
2、Resistance to cold and hot changes (silicone is the best, followed by polyurethane, and epoxy resin is the worst)；
3、After Potting, it is necessary to withstand the temperature (if the temperature is around 100 ℃, then epoxy resin and polyurethane can be used, while organic silicon can withstand high and low temperatures of -40 ℃ to 200 ℃);
4、Thermal conductivity (both epoxy resin and silicone have good thermal conductivity, while polyurethane has the worst)；
In addition to the above factors, we can also consider other factors, such as the internal stress borne by the components, whether they are used outdoors or indoors, the stress situation, whether flame retardancy, color requirements, and manual or automatic potting are required.
Today we will analyze the introduction of various well-known electronic potting adhesive manufacturers:
