Evonik expands its TEGO® Therm product range to provide heat protection and fire-resistant coatings for electric vehicle (EV) battery housings and covers. In the rapidly growing EV market, safety standards for lithium-ion batteries are becoming increasingly stringent.
Coatings based on Evonik's TEGO® Therm products are a robust solution to the industry's demand for effective thermal insulation barriers. They are essential for preventing thermal runaway in EV batteries.
Suitable for Electric Mobility Sector
The TEGO® Therm toolbox includes a variety of components, each meticulously engineered to enhance the performance of thermal insulation and fire-resistant coatings. Among these,
TEGO® Therm HPG 4000 granules boast a microporous silica core. It provides superior low thermal conductivity, high hydrophobicity, and reduced flammability.
TEGO® Therm HPG 6806, a finer silica-based granule excels in insulation. It also strengthens mechanical performance and ensures smooth, even surfaces of insulation coatings.
TEGO® Therm L 300 is a waterborne polysiloxane hybrid binder. It enhances thermal stability and fire resistance of protective coatings.
Dr. Benjamin Schaeffner, global head of Market Segment Industrial and Transportation Coatings at Evonik Coating Additives, said, “
With the electric mobility sector accelerating, the safety of lithium-ion batteries in EVs has never been more crucial. TEGO® Therm is our response to the industry's call for reliable thermal barriers that not only meet but surpass the stringent safety standards of today."
Coatings based on this range of products meet the UL 94 V-0 fire safety standards. This provides a new level of protection for EV batteries. The versatility of TEGO® Therm allows for spray application on complex three-dimensional substrates. It ensures complete and efficient fire resistance of the coverage of every contour of the battery housing.
“
The synergy between TEGO® Therm binder and granules is at the core of our solution. It minimizes heat transfer and effectively inhibits the spread of fires, offering crucial additional time for emergency response,” said Dr. Niko Haberkorn, global head of Business Development for the Market Segment Industrial & Transportation Coatings at Evonik Coating Additives. “
Moreover, our products ensure high mechanical resistance, maintaining structural integrity in high-temperature scenarios.”
Insulation Against Intense Heat
Evonik's commitment to safety and innovation is demonstrated by rigorous testing. 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. These results underscore the effectiveness of TEGO® Therm in insulating against intense heat. This also highlights its suitability for applications where space is at a premium.
The expansion of TEGO® Therm products represent a significant advancement in EV battery safety. As the electric mobility market continues to expand, Evonik's commitment to providing cutting-edge, reliable, and efficient coating solutions will play a pivotal role in shaping a safer and more sustainable future for the
automotive industry.
