Thermal paste PROLIMATECH PK-Zero, thermal conductivity 8 W/m·K, weight 600 g

PROLIMATECH PK-Zero is a thermal interface compound supplied in a 600 g package and formulated to improve heat transfer between electronic components and heatsinks. With a measured thermal conductivity of 8 W/m·K and a density of approximately 2.6 g/cm³, this compound fills microscopic surface imperfections to reduce thermal resistance. The PK-Zero is intended for multiple applications where a high-volume, non-conductive thermal paste is required for CPU, GPU and industrial cooling tasks.

Advantages

PK-Zero provides a balance of thermal performance and practical handling: a thermal conductivity rating of 8 W/m·K, easy application, no required burn-in period, and resistance to dry-out over long service intervals. The compound is not electrically conductive, reducing the risk of short circuits during application. Supplied in a 600 g container, it supports repeated use for servicing multiple systems or large-scale maintenance jobs.

Suitable for

• High-volume servicing of desktop and server CPUs
• GPU maintenance and repasting in workstations
• Industrial cooling assemblies and thermal maintenance
• Workshops and service centers that require bulk thermal compound

Key specifications

• Thermal conductivity: 8 W/m·K
• Weight: 600 g package
• Density: approximately 2.6 g/cm³
• Non-electrically conductive formulation
• Long lifespan with low dry-out tendency

How to use

Clean the mating surfaces thoroughly to remove old thermal compound, dust and oils before applying PK-Zero. Apply a thin, even layer of paste to the component surface or heatsink contact area; the nanoparticle-filled formula is designed to fill microscopic gaps under compression. Mount the heatsink with even pressure to spread the compound and establish thermal contact. No burn-in time is required; monitor temperatures after installation to confirm proper contact and cooling performance.

Recommendations

For best results, use appropriate application tools (spatula or syringe attachments) to control layer thickness and avoid excess. Store the unopened container in a cool, dry place and reseal after use to limit exposure to air. When servicing multiple systems, periodically check that the paste maintains pliability and replace if it shows signs of significant drying or contamination.
