Rubber surface polarity modification: HenkelRecent Research Landscape

Poor interfacial adhesion between rubber and metal leads to catastrophic bond failure and high scrap rates. These innovations engineer the substrate surface energy to ensure robust chemical cross-linking.

What technical problems is Henkel addressing in Rubber surface polarity modification?

Poor interfacial adhesion strength

(8)evidences

Low surface energy and non-polar characteristics of rubber prevent strong chemical attachment to other materials. Overcoming this limitation ensures structural integrity in multi-material composite systems.

Poor interfacial surface adhesion

(5)evidences

Incompatibility between thermosetting films and thermoplastic surfaces leads to delamination and structural failure. Improving surface energy ensures mechanical integrity in high-stress aerospace and automotive applications.

Insufficient interfacial adhesion energy

(4)evidences

Inherent low surface energy of plastic and rubber substrates prevents effective chemical or physical bonding. Overcoming this limitation is critical for structural integrity in multi-material assemblies.
