HC300 is a white poultice organic silicone compound,which enjoys excellent characteristics,such as thermal conduction,electric resistance,weather-wearing,anti- ultraviolet radiation,anti-pollution as well as moistureproof and insulation.It is suitable for the coating of appliance/electric product, brings convenience to apply. 

Properties and Applications

1.It has excellent characteristics such as heat conduction,heat discrimination.
It can work long time under temperature(-50℃-200℃).Its viscosity changes a little when the temperature changes,lies in non-melting under high temperature,non-induration non-freezing in low temprature.
3.No corrosion to metal,copper,aluminum as well as alloy and multi-compound materials.No expansion to plastics and rubber.
4. It's an ideal medium materials to electronic components.Mainly in 
electrics,appliances(induction cooker,fridge,drink machine,E-thermos),electrics(swich power supply,relay,frequency conversion supply,controllable silicone,etc),computer CPU,control panel,display card,LCD display,ray communication equipments,LED and widely used in electronical and wiring field .This serious of products has been attested by international environment-protection SGS,and can meet the standard of European union's inspection standard.
