[0002] Thermally conductive potting compound is a two-component condensation-type thermally conductive potting compound that can reliably protect sensitive circuits and components over a wide range of temperature and humidity. It has excellent electrical insulation properties and can withstand environmental pollution, preventing damage to products caused by stress, vibration, humidity and other environmental factors. It is suitable for insulating and thermally conductive potting of products such as electronics, power modules, high-frequency transformers, connectors, sensors, electric heating components and circuit boards.
[0003] The fluidity of thermal potting adhesive during use is related to its potting effect. Therefore, after processing, thermal potting adhesive needs to undergo fluidity evaluation.
