With its Tego Therm product portfolio, Evonik is opening up applications in heat-resistant and fire-retardant coatings, for example for the battery housings of electric vehicles. Tego Therm is a high-performance solution for effective heat and fire-resistant coatings. "The connection between the Tego Therm binder and the granulate is the heart of our solution. It minimizes heat transfer and thus effectively inhibits the possible spread of fire, which provides crucial additional time for emergency measures in the event of a fire," says Dr. Niko Haberkorn, Global Head of Business Development for the Industrial & Transportation Coatings market segment at Evonik Coating Additives.
Tego Therm portfolio
- The Tego Therm portfolio includes products such as Tego Therm HPG 4000, a granulate with a silica core. The microporous acid ensures low thermal conductivity, high hydrophobic properties and low flammability.
- Tego Therm HPG 6806 is a finer silica-based granulate. In addition to its insulating properties, it improves mechanical resistance and ensures smooth, even coating surfaces.
- The aqueous polysiloxane hybrid binder Tego Therm L 300 also improves thermal stability and is crucial for the flame retardancy of protective coatings.
Tests confirm the safety aspect
When exposed to a propylene flame with a temperature of over 1,000 °C, coatings based on Tego Therm binders and granules effectively protect the substrate. The temperature on the back of the coated substrate remains moderate despite the low film thickness.
Application by spraying
The simple spray application of the coating enables comprehensive and efficient protection, even on complex three-dimensional surfaces.
