The Openair® Plasma process makes it possible for the first time to achieve reliable results when using newly developed one-component warm-melt polyurethane (PUR) adhesives on non-polar plastics, such as polypropylene. Pretreatment with Openair® Plasma generates the required high surface tension on the materials to be bonded.
The technique for combining Openair® Plasma with warm melt adhesives was successfully developed in collaboration with adhesives manufacturer Sika.
