Frequently asked questions
Does P12 conduct electricity?
No. The paste conducts heat (0.6–0.8 W/m·K) but is electrically insulating (dielectric strength approx. 10 kV/mm).
Does the paste dry out or leak oil?
It does not cure, and bleeding is very low at max. 0.4 % (30 h at 200 °C), so hardly any oil migrates onto neighbouring components.
