THERMASOLV IM6 : Unfazed by humidity challenges, a stable and reliable dual-phase cooling shield

In the field of two-phase immersion cooling, where ultimate heat dissipation efficiency is paramount, reliability is key to success. Inventec’s  THERMASOLV IM6  dielectric thermal conductivity fluid not only inherits the ultra-low GWP  and extreme performance characteristic of the Inventec product line , but also, thanks to its excellent water stability , makes it an ideal choice for humid or water-contact-risk environments.

A prime example of high-efficiency dual-phase heat dissipation: ultra-low GWP and a low boiling point of 47°C unleash your computing potential.

  • Insulating heat conduction fluid
  • Boiling point: 47°C/117°F
  • No flashpoint & ultra-low GWP

Core Product Advantages

THERMASOLV™ IM6 is designed to provide a versatile cleaning path that can handle complex thermally conductive interface materials (TIMs) while also ensuring the cleanliness of precision parts.

  • Multi-effect dissolving power: Designed to remove thermal grease, silicone oil residue, light lubricating grease, and machining fingerprints , ensuring atomic-level purity of part surfaces.
  • Low surface tension penetration: Its excellent wetting properties allow it to easily penetrate into tiny gaps and precision threads, completely suspending and removing hidden dirt.
  • Extremely high safety (High Flash Point): The flash point is much higher than the normal operating temperature, which greatly improves the safety of operation in automated cleaning lines and immersion tanks.

Safety & Environmental Commitment

As Taiwan’s technology industry shifts towards low-carbon production, IM6 offers a more sustainable chemical option.

  • Ultra-low VOC and environmentally friendly: It has an extremely low evaporation rate, which can effectively reduce the emission of volatile organic compounds (VOCs) in the factory and comply with Taiwan’s air pollution control regulations.
  • Zero Ozone Depletion (ODP): It has no burden on the atmosphere and meets the high environmental protection standards required by the global electronics supply chain for suppliers.
  • Harmless halogen-free formula: Free of nPB or chlorinated solvents, reducing the complexity of chemical management (SDS) and protecting the health of frontline employees.

Exceptional Performance

IM6 provides the most reliable guarantee for Taiwan’s high-end electronics manufacturing industry’s stringent requirements for “material compatibility”.

  • Excellent material protection: It is not corrosive to aluminum alloys, gold-plated parts, stainless steel and engineering plastics commonly used in precision semiconductor equipment , and can maintain the original surface gloss of the components.
  • Long-lasting and stable tank life: The solvent has extremely high chemical stability and load-bearing capacity, and it is not easy to deteriorate even under long-term operation, maintaining stable cleaning quality.
  • Dry and residue-free: With proper drying processes, it is possible to ensure that there are no solvent spots or oil films on the surface of the parts, laying a perfect foundation for subsequent coating, encapsulation or assembly.

Cost optimization

IM6 leverages its physical properties to help businesses achieve energy and cost savings in their daily production processes.

  • Extremely low material loss: Due to its extremely slow evaporation, the annual solvent replenishment in an open-type immersion system is reduced by more than 50% compared to traditional fast-drying solvents.
  • Cleaning without heating: It can exert excellent dissolving efficiency at room temperature, which greatly reduces the power consumption of large cleaning equipment.
  • Reduced wastewater treatment burden: Longer service life and lower consumption mean less waste chemicals are generated, directly optimizing environmental treatment costs.

Application area 

  • Semiconductor packaging and repair: Cleaning silicone grease from lead frames, heat sinks, and related packaging molds.
  • Precision optical and medical instruments: Removes light grease and grime from the assembly process.
  • Power electronics modules: large-scale immersion cleaning of heat sinks for inverters or converters.
  • Aerospace and military parts: Cleaning of precision mechanical components with extremely high requirements for safety and material integrity.
