COOL SILVER™ G5

1 of 8 products in this brand
COOL SILVER™ G5 is an improved version of COOL-SILVER™ G3 and G4. It is a non-curing, non-silicone, thermal interface modified silver-filled grease that is not electrically conductive in bulk. The non-curing COOL SILVER™ G5 is by far the lowest thermal resistance grease that is not electrically conductive when compared with the best of the silver and diamond greases. It is designed specifically for high-power devices requiring less than 0.0015 °C-in²/watt thermal resistance (0.001 inch interface layer). COOL SILVER™ G5 will become a slightly more viscous after dispensing.It will remain as a thermally conductive interface medium with non-electrically conductive properties at all time. Temperatures greater than 100°C, will cause grease to gel.
