High-Grade Nano Aluminium Compound

Prolimatech PRO-PK2-1.5G is a 1.5 gram syringe of nano aluminium thermal compound built for PC builders who need reliable heat transfer between a CPU or GPU die and a cooler base. The material blends aluminium, zinc oxide, oil and antioxidant into a non-corrosive, electrically non-conductive paste that requires no burn-in period. Its low viscosity lets you spread the thinnest possible layer quickly, making it ideal for first-time builders and experienced overclockers alike who value a clean, straightforward application.

Thermal Conductivity and Long-Term Stability

The compound delivers a thermal conductivity of 10.2 W/m-Degree C and a thermal impedance of 0.015 Degree C-in2/W, providing efficient heat flow under normal operating loads. Adhesiveness is rated at 250000 Cps, giving the paste enough body to stay in place without migrating over time. The formula resists dry-out and maintains consistent performance across a wide temperature range, so thermal resistance remains stable through extended gaming or workstation sessions without the need for frequent re-application.

Easy Integration Into Any Build

Supplied in a compact 1.5 g syringe with a specific gravity of 2.5 g/cm3, the paste fits easily into a toolkit and covers multiple installations without waste. Because it is electrically non-conductive, accidental contact with surrounding components poses no short-circuit risk, simplifying cleanup around socket areas. The non-corrosive composition protects copper, aluminium and nickel-plated cold plates, while the low dry-out characteristic means the interface remains effective for years, freeing the builder from scheduled maintenance cycles.

Questions about this item

How do I apply the PK-2 paste and what step do people usually get wrong?

The low 250000 Cps viscosity lets the paste spread thinly under pressure; the common error is applying too much instead of a small dot or thin line.

Will the PK-2 compound dry out or need replacement after a few years?

The formula uses 11~19 wt% oil with antioxidant for low dry-out and long-term stability, so it typically lasts many years without reapplication.

At what thermal load does the 10.2 W/m-? conductivity become the limiting factor?

The 0.015 ?-in²/W impedance means the paste itself rarely limits cooling; the bottleneck is usually the cooler base or heat-spreader contact quality.
