Thermon T-99

High-temperature Heat Transfer Compound


Thermon T-99 stands out as a specialty high-temperature heat transfer compound, meticulously formulated to deliver exceptional performance in demanding environments. With a remarkable thermal stability and bond strength reaching up to 1204°C (2200°F), T-99 ensures reliability even in extreme conditions. Notably, unlike other heat transfer compounds, it boasts electrical non-conductivity when cured, providing an added layer of safety.

Supplied ready for use, T-99 can be conveniently applied by hand troweling to fill TFK channels, simplifying installation processes. Resistant to thermal and mechanical shock, this compound offers efficient heat transfer with a high bond strength, ensuring longevity and performance.

To maximize effectiveness, proper surface preparation is crucial. Surfaces of traced valves, pumps, and other equipment must be meticulously cleaned to remove oil, grease, dirt, rust, scale, and other contaminants. Common pre-treatment techniques such as solvent and emulsion application, along with scraping, chipping, and wire brushing, promote optimal surface wetting and ensure proper contact for T-99 application. With its exceptional thermal stability, bond strength, and ease of application, Thermon T-99 sets the standard for high-temperature heat transfer compounds in challenging industrial environments.
