Thermal paste PROLIMATECH PK-2, thermal conductivity 10.2 W/m·K, 5 g

PROLIMATECH PK-2 is a thermal interface compound with a specified thermal conductivity of 10.2 W/m·K and a net weight of 5 g. Developed for improving heat transfer between CPUs, GPUs and heatsinks, PK-2 features low viscosity to enable thin, even spreads that reduce thermal resistance. The paste is supplied in a small 5 g quantity suitable for single or occasional applications during PC cooling upgrades, maintenance or rebuilds.

Advantages

PK-2 offers a high thermal conductivity rating of 10.2 W/m·K combined with a low-viscosity formula that makes application smooth and precise. The compound is formulated to create close contact between the chip surface and heatsink without requiring excessive pressure or large quantities. Its small 5 g packaging is practical for users who need a high-performance paste in limited amounts.

Suitable for

• Applying or replacing thermal paste on desktop CPU and GPU coolers
• Upgrading cooling systems in gaming PCs and workstations
• Maintenance and reassembly after cleaning heatsinks and fans
• DIY builds and occasional repairs where a high-conductivity paste is required

Key specifications

• Thermal conductivity: 10.2 W/m·K
• Net weight: 5 g
• Low viscosity for easy spreading and thin layer application
• Designed for use between semiconductor package surfaces and metal heatsinks

How to use

Clean both the component surface and heatsink mating surface thoroughly to remove old thermal compound, dust and oils. Apply a pea-sized amount of PROLIMATECH PK-2 to the center of the CPU or GPU die or follow your cooler manufacturer’s recommended application pattern. Mount the heatsink and secure it according to the cooler's instructions, allowing the paste to spread and form an even contact layer. If excess compound is squeezed out, clean the edges with isopropyl alcohol and a lint-free cloth.

Usage recommendations

Use PK-2 for single or occasional applications where high thermal conductivity and easy spreadability are important. Avoid contaminating the paste with dirt or moisture, store the tube capped in a cool, dry place, and replace if the paste changes color or consistency. For optimal thermal transfer, ensure even mounting pressure and a clean mating surface prior to application.
