Pressure Sensitive Adhesives

Pressure Sensitive Adhesives (PSAs) are adhesives which form a bond when pressure is applied to marry the adhesive with the adherend (or substrate).

As the name “pressure sensitive” indicates, the degree of bond is influenced by the amount of pressure which is used to apply the adhesive to the surface. Surface factors such as smoothness, surface energy, removal of contaminants, etc. are also important to proper bonding.
