1.0 W/mK Non-Curing Insulating Thermal Grease Thermal Conductive Silicone Grease for Sensor and Printer Head Cooling

HN100 is a single-component, non-curing thermally conductive silicone grease built for precise thermal coupling of small, heat-sensitive components. It maintains a stable paste consistency from −50 °C to +200 °C, provides 1.0 ± 0.1 W/m·K thermal conductivity with 2450 V/mm electrical insulation, and shows very low oil separation (≤ 0.3%) and volatility (≤ 0.6%). The soft, low-penetration paste wets irregular surfaces evenly, making it suitable for temperature sensors, thermistors, printer heads and other components where consistent contact pressure and thin bond lines matter.

• Thermal conductivity: 1.0 ± 0.1 W/m·K (ASTM D5470)
• Non-curing: stays paste-like indefinitely, no hardening, no drying, easy rework
• Wide operating range: −50 °C to +200 °C; no powdering after 8 days at 200 °C
• Electrical insulation: breakdown voltage 2450 V/mm at 0.20 mm (IEC 60243)
• Low bleed and low volatility: oil separation ≤ 0.3%, volatile matter ≤ 0.6% at 200 °C / 24 h
• Soft consistent texture: penetration 370 ± 20 (1/10 mm) for uniform wetting of sensor housings and print heads
• Production friendly: suitable for brushing, rolling, automatic dispensing and screen printing
• Compliance: RoHS 2.0, non-toxic, odourless and non-corrosive

HN100 is designed for thermal coupling and heat dissipation across small and medium electronic assemblies:

• Temperature sensing: thermistors, temperature sensors, thermal switches and sensor housings requiring stable thermal contact
• Printing equipment: printer heads, thermal print bars and imaging modules
• Heating components: heating elements, heat strips, heating plates and heat exchange strips
• Power supplies: regulated power supplies, voltage regulators, switching power supplies and power supply modules
• Microwave and RF devices: surface coating and full encapsulation of microwave devices, microwave communication systems and microwave transmission equipment
• Power semiconductors: power transistors, thyristors and power modules mounted on heat sinks or housings
• Computing and consumer electronics: CPU assemblies, GPU heat sinks, notebooks and graphics cards
• Automotive and lighting: automotive electronics, car refrigerators, LED lighting fixtures and LED driver heat sinks

All values are measured under standard conditions and are for reference only. Actual thermal performance may vary with application conditions, bond line thickness (BLT) and contact pressure.

1. Surface preparation: clean all contact surfaces with a solvent to remove grease, dust and oxidation; ensure surfaces are completely dry.
2. Application: apply a thin, even layer by brushing, rolling, automatic dispensing or screen printing.
3. Spreading: use a clean razor blade, plastic spatula or clean knife to spread the paste evenly over the sensor, print head or heat sink interface.
4. Thickness control: keep the bond line as thin as possible for the best heat transfer; wipe excess from edges with a lint-free cloth.
5. Assembly: mount the component or heat sink immediately and apply the specified clamping force or torque to secure a uniform bond line.

• Packaging: 1 kg plastic drum, 5 kg plastic drum; custom package sizes available upon request
• Storage: keep containers tightly sealed in a cool, dry, well-ventilated area away from direct sunlight; recommended below 27 °C
• Shelf life: 12 months from date of manufacture when stored unopened and properly sealed
• Transportation: classified as non-dangerous goods; handle with care to prevent leakage
