24 May 2023 --- Henkel has extended its electric vehicle (EV) battery systems portfolio with a “first-of-its-kind” injectable thermally conductive adhesive. The new adhesive, branded Loctite TLB 9300 APSi, provides the battery system’s structural bonding and thermal conductivity. Due to its precise application, enhanced design flexibility and improved bond strength, the injectable thermally conductive adhesive offers the benefits of a simplified manufacturing process. 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-leveling characteristics. It is designed for bonding battery cells to modules or bonding cells directly to cooling systems.Henkel says the adhesive delivers a “unique” combination of good electrical insulation with high bonding performance to various substrates. As a solvent-free solution that cures at room temperature without additional energy consumption, it helps customers advance their environmental sustainability agenda by reducing emissions and resource use while ensuring safer working environments.
