Henkel Adhesive Technologies, a maker of automotive adhesives, sealants, thermal materials and functional coatings, has extended its portfolio of solutions for EV battery systems with a new injectable thermally conductive adhesive. The new adhesive, Loctite TLB 9300 APSi, provides both structural bonding and thermal conductivity in the battery system. Henkel says the new product has already been adopted by a major EV battery manufacturer.
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’s designed to deliver a combination of good electrical insulation with high bonding performance to a variety of substrates. It’s a solvent-free solution that cures at room temperature without the need for additional energy consumption.
“Loctite TLB 9300 APSi is a testament to Henkel’s continued efforts to innovate new e-mobility solutions tailored to solve today’s battery manufacturing challenges and enable the next-generation designs of tomorrow,” said Holger Schuh, Global Senior Manager Thermal Technologies at Henkel. “Its immediate adoption by a major battery manufacturer demonstrates our close partnership with key players in the e-mobility industry.”
“Thermal management in EV batteries is still one of the biggest challenges for electrified mobility,” says Stephan Hoefer, Global Market Strategy Head for E-Mobility at Henkel. “New designs targeting higher energy densities in battery packs bring the requirement for multifunctional thermally conductive adhesives instead of classical thermal gap fillers. Leveraging our strong innovation capabilities at Henkel, we have started to launch a family of materials varying in thermal conductivity, bonding strength, elasticity, and application methods to address those new requirements.”
