Our Thermally Conductive Adhesives (TCAs) provide:

Temperature resistance: TCAs can work well in temperatures ranging from -40°C to 150°C. This allows the EV battery to function effectively during charging, discharging, and regular use at various temperatures.

Durability: TCAs protect against degradation with chemical, UV and humidity resistance. TCAs are also formulated to be compatible with metals, ceramics or plastics to prevent reactions between the adhesive and bonded materials. This helps reduce the likelihood of battery maintenance and replacement

Flexibility: Some TCAs are designed to remain flexible even after curing, which helps account for expansion and contraction as battery components experience heating and cooling. Flexible TCAs have the ability to absorb the stress to reduce the likelihood of mechanical failure.

Our Thermally Conductive Adhesives Solutions

We offer thermally conductive adhesives which are polyurethane, or epoxy based with strong mechanical adhesion and thermal conductivity. The formulations are tunable, so we can play on the viscosity, the strength, the flexibility and the open time to fit better your needs.

  • 2K EP TCAs are non-silicone solutions that often are chosen for high-strength bonding, with the ability to adjust the properties to your specific needs in battery design. As a low-density, non-silicone solution, they offer a variety of viscosity ranges for fast joining and automated processes. They also provide excellent chemical resistance to enhance the overall battery lifespan.
  • 2K PUR TCAs provide thermal conductivity up to 1.5 W/m.K or higher*. They are often chosen for their heat dissipation in battery pack assembly, possessing high elongation that enables elasticity for thermal expansion and contraction during heating and cooling. 2K PUR adhesives bond to substrates such as nylon, aluminum or steel and help ensure the components stay electrically isolated to help reduce electrical fault risks.

Our innovation 

The new XPU TCA 202 is a two-component, polyurethane-based adhesive specifically designed for heat dissipation in battery pack assemblies. It perfectly tackles the challenge to balance thermal conductivity with high mechanical strength while maintaining good levels of flexibility thanks to high elongation.
