(Non-reactive) Hotmelt adhesives
Non-reactive hotmelts adhesives belong to the group of physically setting adhesives, where the setting takes place without any chemical change to the polymer. Before application, the adhesive is heated and starts to melt, typically at temperatures above 100 °C. The adhesive is then applied in liquid (molten) form to the substrate. A physical setting takes place during cooling, which turns the hotmelt back into a crystalline or amorphous solid.
