PEEL BEHAVIOR OF PRESSURE-SENSITIVE ADHESIVES

Studies on the dependence of the peel strength on the rate of separation have shown that the peel behavior is influenced greatly by the interfacial interaction. The introduction of carboxyl groups in the surface of an adhesive resulted in the high peel strength at the wide range of rates and varied the shape of the whole curve; whereas the effect of carboxyl groups was diminished by the addition of a small amount of surface active agent sufficient for monolayer formation at the adhesive-adherend interface.
