Prolimatech PK-2 Nano Aluminum (Aluminum Nano-Particle/Non-Conductive/Low-Viscosity Compound/10.2 W/mK) Review
Looking up prolimatech pk-2 thermal compound specs to see how it differs from the PK-1? The two share a conductivity rating but not much else.
PK-2 is Prolimatech's easier-to-spread compound, same 10.2 W/mK rating as the PK-1 but noticeably lower viscosity, so it's the one we'd grab for anyone who wants a thin, even layer without fighting the paste.
Thermal Performance
10.2 W/mK ties the PK-1 and sits behind the PK-3 Nano Aluminum already in this catalog, but real-world performance depends heavily on how thin and even you can spread it, which is exactly where PK-2 has the edge.
Application
Lower adhesiveness (250,000 cP vs the PK-1's 310,000 cP) makes this noticeably easier to spread thin, Prolimatech markets low viscosity as PK-2's core selling point.
Safety
Rated to a 4 KV/mm dielectric strength and non-electronically conductive.
