Thermal Grizzly has expanded its thermal interface material lineup with the introduction of the new Duronaut Pro and Hydronaut Pro thermal pastes. Building upon their respective predecessors, the new Pro variants deliver improved thermal conductivity while retaining the characteristics that made the original formulations popular among enthusiasts and professionals.

Although the temperature gains over the standard Duronaut and Hydronaut are relatively small, Thermal Grizzly notes that further improvements in thermal paste performance are increasingly difficult to achieve. The company considers the enhancements significant, particularly for users seeking every possible degree of cooling efficiency in high-performance systems.

Duronaut Pro – Designed for Maximum Longevity
Duronaut Pro is a premium thermal paste developed with a focus on both improved thermal conductivity and long-term stability. The formulation combines aluminium micropowder with zinc oxide nanopowder and a specially developed silicone oil to minimise the pump-out effect and maintain performance over extended periods.

Optimised particle sizes and shapes allow the paste to be applied in a very thin layer, reducing thermal contact resistance and improving heat transfer between the processor and cooler. Duronaut Pro is also supplied with the new TG Spatula Pro, which is designed to help spread the compound more evenly.

• Extreme long-term stability
• Improved thermal conductivity over Duronaut
• Electrically non-conductive
• No curing or hardening over time
• Reduced pump-out effect
• Thin application layer for lower thermal resistance
• Includes TG Spatula Pro

Hydronaut Pro – Silicone-Free Formula for Industrial Applications
Hydronaut Pro has been engineered for users requiring a silicone-free thermal interface material. Unlike conventional thermal pastes that rely on silicone-based oils, Hydronaut Pro uses a silicone-free carrier structure, making it suitable for industrial environments where silicone oils may adversely affect seals and neighbouring materials.

The compound is designed to resist degradation caused by thermal cycling and remains easy to apply. Thermal Grizzly also highlights its RoHS compliance and suitability for demanding applications requiring reliable heat transfer without the use of silicone-based components.

• Silicone-free carrier structure
• Suitable for industrial applications
• Improved thermal conductivity over Hydronaut
• Electrically non-conductive
• No curing over time
• Resistant to pump-out effects
• RoHS compliant

Pricing and Availability
Thermal Grizzly offers Duronaut Pro in 2g, 6g, and 30g variants, with pricing starting at USD 20.94. Hydronaut Pro is also available through Thermal Grizzly's online store. Additional regional pricing and availability may vary.
