Kootai 9920 Thermally Conductive Compound is a non-curing, high-performance thermal interface material (TIM) formulated to fill air gaps and promote efficient heat transfer between electronic components and heat sinks. This silicone-based paste offers a unique blend of low volatility (≤0.2%), minimal oil bleed (≤1.0%), and stable cone penetration (180–210 mm) to maintain consistent performance across thermal cycles.
With a dielectric strength of 22 kV/mm, volume resistivity of 3.0×10¹⁵ Ω·cm, and thermal resistance of 0.25 °C·in²/W, 9920 provides excellent electrical insulation and safety. It is non-toxic, odor-free, RoHS- and REACH-compliant, and available in White (W), Black (B), and Grey (G).

FAQ
Q1: What is 9920 used for?
A: It's designed as a thermal interface for CPUs, ICs, LEDs, MOSFETs, power modules, and heat-generating electronics.
Q2: Does it harden or cure over time?
A: No, it remains a grease. It does not require curing and retains flexibility, making it easy to rework.
Q3: Is it electrically insulating?
A: Yes. It has high dielectric strength (22 kV/mm) and excellent volume resistivity (3.0×10¹⁵ Ω·cm), ensuring electrical insulation.
Q4: Is it compatible with plastics or metals?
A: Yes. It adheres well to most surfaces like aluminum, copper, plastics, and glass without corrosion.
Q5: How should it be stored and applied?
A: Store in a cool, dry place away from sunlight. Clean the substrate, then apply the paste directly between surfaces.
