ABSTRACT

Pressure-sensitive adhesive (PSA) properties are typically characterized by three types of standard tests, peel tests, shear tests, and tack tests (see also Applications of PressureSensitive Products, Chapter 8). Th e latter type of test is designed to probe the ability of the PSA to stick on a surface under a light applied pressure. Th e test is oft en carried out with a loop of tape (loop tack test; see also Applications of Pressure-Sensitive Products, Chapter 8) or by testing the rolling resistance of a steel ball on the adhesive1 (see also Applications of Pressure-Sensitive Products, Chapter 8).
