Ancamide® & Ancamine®


Flexible polyamide curing agents for epoxy adhesives

Bonding dissimilar substrates will be key

Stricter regulations on fleet consumption and CO2 emissions are driving the demand for energy-efficient and environmentally-friendly mobility options, leading to increased momentum for electric mobility solutions and a technological transformation in the automotive industry. While electric vehicles are gaining market share, challenges remain in manufacturing processes, mainly related to new battery concepts and lightweight design. This has led to a greater use of dissimilar materials, and tailored adhesive solutions are now playing a crucial role.

Key benefits of Ancamine® & Ancamide® 2K ADHESIVES curing agents

Addressing these challenges, Evonik has created a line of flexible curing agents specifically designed for use with epoxy adhesives, such as Ancamide® 910, Ancamine® 1922A and Ancamine® 2638, which are ideal for bonding dissimilar materials. Adhesives formulated with these curing agents exhibit exceptional adhesion and peel strength without any additional surface preparation, making them suitable for use with materials like steel, aluminum, and engineering plastics. The curing agents’ flexible backbones provide good flexibility and thermal shock resistance to adhesives which is complemented by an outstanding environmental resistance. Additionally, their relatively low viscosities also allow for the formulation of higher filled adhesives applied as thermal interface materials for instance.

These unique properties along with options for different viscosities, gel times, use levels and glass transition temperatures make Ancamide® 910, Ancamine® 1922A and Ancamine® 2638 a valuable toolbox for those in the automotive industry looking for solutions in lightweight as well as efficient electric vehicle production.
