Bonding to dirt-repellent nano-coatings – excellent adhesion thanks to Openair® Plasma

Modern lotus-effect nano-coatings and ultra-hydrophobic topcoats make it possible to produce highly dirt-repellent surfaces. The downside is that such surfaces have a very low surface tension.

 Bonding model nameplates

Various adhesives manufacturers claim to offer products capable of bonding to such coatings. However, such adhesives can only be used within a narrow process window (temperature or humidity) and have a limited open time.

Pretreatment of hydrophobic and non-polar coatings with Openair® Plasma enables efficient and selective activation of surfaces, resulting in long-term adhesion. This simple method makes it possible to achieve reliable results with VOC-free adhesives with longer open times, for example when bonding door seals, trim strips and model nameplates.
