In previous articles, the fundamental of viscoelasticity and the principle of adhesion were briefly discussed. A material must cold flow at room temperature in order to possess pressure sensitive features. Disregarding polymer bases and the use of tackifiers, all room temperature applied “general purpose” pressure sensitive adhesives (PSAs) should meet the following rheological criteria… Read Article>>
