AG Silver thermal grease - 0.5g is added silver compounds, use the high thermal conductivity of silver to make up the shortage of the carbon-silicon compounds. The color of the thermal grease is silver, the thermal conductivity is much higher than the common carbon-silicon compounds. Ideal as a transmitter of heat from the heat pipe condenser to exchanger in a vacuum solar collector.
