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.
