Henkel introduces thermal gap filler and thermal adhesive to enhance electric vehicle battery thermal management performance

As electric vehicle battery systems continue to evolve toward higher energy density, faster charging capabilities, and entirely new architectures, effective thermal management is becoming increasingly critical. To help automakers and battery manufacturers address these challenges, Henkel has launched two new thermal interface materials for EV batteries:Bergquist TGF 2030APS (silicone-free, two-component thermal gap-filling material) and Loctite TLB 9270APS (polyurethane-based, two-component thermally conductive adhesive).

These two materials are designed to help manufacturers meet the ever-increasing performance requirements of modern EV battery systems while supporting high-volume, cost-effective production.

Bergquist TGF 2030APS: High-Speed Application, Lower Energy Consumption

With a thermal conductivity of 1.7 W/m·K Bergquist TGF 2030APS effectively transfers heat from the cell stack in the battery module to the cooling plate. It can be applied at speeds of more than 40cc per second. Its silicone-free formulation and low compression force help reduce the risk of damaging batteries during assembly, making it suitable for sensitive battery applications.

In addition, the product is designed to help reduce the carbon footprint, reflecting Henkel’s strategic focus on developing lower-emission, more sustainable product solutions. Itsroom-temperature curingcapability further supports energy-efficient processing during assembly, helping manufacturers advance their sustainability goals without compromising performance or production efficiency.

Loctite TLB 9270APS: High-Performance Thermal Bonding

Loctite TLB 9270APS is a two-component polyurethane-based adhesive designed for electric vehicle batteries featuring aCell-to-Packarchitecture. It offers a thermal conductivity of 2 W/m·K while providing high bond strength and electrical insulation, making it particularly suitable for aluminum and PET film substrates.

The product can be applied rapidly to improve production efficiency and provides a 40-45 minute long open time under typical conditions. It is solvent-free and complies with stringent regulatory and safety standards.

Innovation Driven by the Needs of the EV Industry

Dr. Tobias Knecht, Dr. Tobias Knecht Head of Henkel’s global EV market strategy, said: “Henkel is a trusted long-term design and innovation partner to the EV industry, with a strong track record of delivering advanced thermal management solutions for demanding environments. As battery designs evolve rapidly—with capacity continuing to increase and new architectures such as cell-to-pack and cell-to-chassis emerging—we are committed to providing manufacturers with versatile and innovative thermal interface materials to meet these changing needs. The launch of Bergquist TGF 2030APS and Loctite TLB 9270APS is the latest step in fulfilling that commitment.”

Henkel will showcase its latest innovations and newly launched solutions for EV battery systems at theJune 9 to 11 event held at the Stuttgart Exhibition Center in Germany,2026 European Battery Show. Visitors will have the opportunity to experience Henkel’s advanced thermal management technologies firsthand and explore a broad portfolio of materials designed to create safer, higher-performing, and more sustainable next-generation EV batteries.
