Evonik introduces fire-resistant coatings for EV battery housings
Evonik expands its TEGO Therm product range to provide heat protection and fire-resistant coatings for electric vehicle (EV) battery housings and covers.
Evonik expands its product range to provide fire-resistant coatings for EV battery housings and covers.
TEGO Therm product range
The TEGO Therm range includes a variety of components, each engineered to enhance the performance of thermal insulation and fire-resistant coatings. Among these, TEGO Therm HPG 4000 granules boast a microporous silica core, which provides superior low thermal conductivity, high hydrophobicity, and reduced flammability.
TEGO Therm HPG 6806, a finer silica-based granule, not only excels in insulation but also strengthens mechanical performance and ensures smooth, even surfaces of insulation coatings.
The waterborne polysiloxane hybrid binder, TEGO Therm L 300, further enhances the thermal stability and fire resistance of protective coatings.
Versatile and high-performance coating
The versatility of TEGO Therm allows for spray application on complex three-dimensional substrates, ensuring complete and efficient fire resistance of the coverage of every contour of the battery housing.
Coatings in the TEGO Therm range minimize heat transfer and effectively inhibits the spread of fires. They meet the UL 94 V-0 fire safety standards, providing a new level of protection for EV batteries.
When subjected to a propylene flame with more than 1000°C, TEGO Therm-based coatings protected the substrate effectively, with the temperature on the back of substrate remaining moderate, even with a thin dry film thickness.
Moreover, the products ensure high mechanical resistance, maintaining structural integrity in high-temperature scenarios.
