Thermally conductive silicone potting compound is a two-component organic silicon potting adhesive. It fully complies with the EU ROHS directive and SVHC-REACH requirements. Upon mixing, it undergoes an addition reaction to form a high-performance elastomer. This product is designed for harsh environments where waterproofing, moisture resistance, corrosion resistance, and shock absorption are necessary.
The curing speed of this compound is adjustable, and its deep-curing feature is not affected by the environment. Characterized by good thermal conductivity and electrical insulation properties, it is suitable for internal component heat dissipation in high-powered devices, integrated circuit boards, electric vehicle charging column modules, lithium battery packs, photovoltaic inverters, LED power drive modules, and similar applications.
This potting compound is an excellent option for casting, potting, insulation, and sealing large-area and deep-sealed parts, boasting exceptional electrical, high, and low-temperature resistance characteristics.
