2K Adhesives for modern electric vehicles

Ancamide® 910 is a flexible polyamide curing agent for epoxy adhesives that offers better adhesion on dissimilar substrates

Since stricter regulations regarding fleet consumption and CO2 emission targets are increasing the worldwide demand for more energy and environmentally friendly mobility platforms, electric mobility solutions are gaining momentum pushing the automotive industry into a pivotal technological transformation. While electric vehicles continue to capture market share there are still challenges in the manufacturing processes. These stem mainly from new battery concepts and related structural reconsiderations, as well as the emerging importance of lightweight design. Consequently, the combination of dissimilar materials is becoming more common and tailored adhesive solutions are now playing a more decisive role.

To address these more complex demands, Evonik has developed a series of polyamide curing agents tailored for epoxy adhesives. For example, our Ancamide® 910 curing agent is particularly suitable for bonding dissimilar substrates. Besides excellent adhesion and peel strength without any special surface pre-treatment on different materials, such as steel, aluminum or engineering plastics, adhesives formulated with Ancamide® 910 also provide good flexibility and thermal shock resistance with an outstanding environmental resistance. In addition, Ancamide® 910 has a relatively low viscosity which for example, also enables the formulation of higher filled adhesives with thermal conductive properties.

This unique combination of properties makes Ancamide® 910 curing agent an attractive choice for formulators coping with the current and future challenges in lightweight and efficient electric vehicle production.
