Abstract

Adhesive tack is critical in the initial formation of an adhesive bond. However, tack is not a unique property of the adhesive but also depends on the properties of the adherends, the bonding process. Measured tack values will also depend on the test method and conditions. Loop tack, probe tack and rolling ball tests are all commonly used to measure tack for a variety of purposes. A comparison of these methods is presented. The rolling ball test results were significantly different. .Loop and probe tack tests give similar relative rankings of adhesive tape performance. These differences may be explained by differences in the test methods. Experimental studies to illuminate the influence of test variables, such as contact pressure, dwell time, test speed, temperature and adherend stiffness, are discussed. A Finite Element modelling approach was used to study the influence of the stiffness of the backing material in the loop tack test.
