Henkel launches a new injectable thermally conductive adhesive for EV battery systems in order to solve the challenges of OEMs and battery manufacturers. The new adhesive – Loctite TLB 9300 APSi – provides both structural bonding, as well as thermal conductivity in the battery system. The breakthrough product has already been adopted by one of the world’s largest EV battery manufacturers.
Designed for applications such as bonding battery cells to modules, or bonding cells directly to cooling systems, Loctite TLB 9300 APSi is a two-component polyurethane thermally conductive adhesive with a high thermal conductivity of 3 W/mK, moderate viscosity, and self-levelling characteristics. In addition to its heat management properties, it delivers a unique combination of good electrical insulation with high bonding performance to a variety of substrates. As a solvent-free solution that cures at room temperature without the need for additional energy consumption, it helps customers advance their sustainability agenda by reducing emissions and resource use, while also ensuring safer working environments.
