EVALUATION OF PRESSURE SENSITIVE ADHESIVES USING CONTACT ANGLE AND ADHESION TENSION RELAXATION

摘要

When evaluating PSAs using contact angle techniques, it is important to consider the mechanism of mul-ticomponent polymeric systems that reorient their segments in response to the testing medium. It is also worthy of note that measurements of contact angle hysteresis and adhesion tension relaxation are very useful approaches in comparison to static contact angle measurement.
