    Core tip: potting is an important application field of epoxy resin It has been widely used in electronic device manufacturing industry and is an indispensable and important insulating material in electronic industry According to experts from China epoxy resin industry association, potting is a kind of thermosetting polymer insulation material with excellent performance, which is made by pouring liquid epoxy resin composite into electronic components and circuit devices mechanically or manually, and solidifying under normal temperature or heating conditions Its functions are: to strengthen the integrity of electronic devices, improve the resistance to external shock and vibration; to improve the insulation between internal components and lines, which is conducive to miniaturization and lightweight of devices; to avoid components and lines Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Coating home news: potting is an important application field of epoxy resin It has been widely used in electronic device manufacturing industry and is an indispensable and important insulating material in electronic industry According to experts from China epoxy resin industry association, potting is a kind of thermosetting polymer insulation material with excellent performance, which is made by pouring liquid epoxy resin composite into electronic components and circuit devices mechanically or manually, and solidifying under normal temperature or heating conditions Its functions are: to strengthen the integrity of electronic devices, improve the resistance to external shock and vibration; to improve the insulation between internal components and lines, which is conducive to miniaturization and lightweight of devices; to avoid direct exposure of components and lines, and to improve the waterproof and moisture-proof performance of devices The application range of epoxy potting materials is wide, and the technical requirements vary greatly In terms of curing conditions, there are two types: room temperature curing and heating curing; in terms of dosage forms, there are two types: two-component and single component The normal temperature curing epoxy potting material is generally two-component After potting, it can be cured without heating It has low requirements for equipment and is easy to use The disadvantages of the composite are high viscosity, poor permeability, short application period, difficult to achieve automatic production, and the heat resistance and electrical properties of the solidified products are not very high, which are generally used in low-voltage electronic device potting, or not suitable for heating and curing occasions According to the experts from China epoxy Industry Association, the two-component heat curing epoxy potting material is the most widely used product It is characterized by low operating viscosity, good processability, long application period, good permeability and excellent comprehensive properties of the solidified products, which are suitable for the automatic production line of high-voltage electronic devices Single component epoxy potting material needs to be heated and solidified, which is a new type developed abroad in recent years Compared with two-component heated and solidified potting material, the outstanding advantage is that the required potting equipment is simple, easy to use, and the quality of potting products has little dependence on the equipment and process Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
