Acrylic Pressure-Sensitive Adhesives (PSAs): A
PSAs require good contact with the substrate to obtain adhesion. A rough surface will reduce the amount of effective contact area. Stiff adhesives may not be able to flow into the micro-roughness on the surface of the substrate. Therefore, additives may be used to lower the Tg and improve the flow properties as the adhesive is applied.
