TThermally Conductive Silicone Adhesives & Potting Compounds
Two Component 4.0 W/m.K High Thermally Conductive Silicone Potting and Encapsulation Adhesive Sealant
∎Product Description
●SI8230 is two-component silicone based thermal conductive potting adhesive. It is with Thermally Conductive, two parts, low viscosity potting compound that cures at room temperature to a soft pliable rubber. Will cure in deep sections. Designed to achieve primerless adhesion to many substrates, including metals, plastics, and ceramics.
It has a good fluidity after mixing, can vulcanize to deep layer in room temperature. The operation time can be adjusted according to the temperature. Used to potting protection of varied heat dissipation and temperature resistance components. Fully compliant with RoHS and SVHC REACH standard.
8230 thermally conductive silicone encapsulants can be used in potting applications to dissipate heat away from a component to a suitable heat sink. They also provide protection from harsh environments, vibration and thermal shock. Addition cure silicones provide deep section cure allowing for complete encapsulation for environmental protection whilst maintaining an effective heat path.
∎Application
●Used for encapsulation of various modules, automotive module, LED Power driver modules, Solar panel junction box, EV charging column module, Lithium battery pack, Capacitor banks, Magnetic induction coils, Power inverters, etc.
