The ASTM D2979 test method provides a quantitative measure of the pressure-sensitive tack of the adhesive. The method is designed to evaluate the adhesive mass itself and is suitable for measuring the tack of pressure-sensitive adhesives for use on both rigid and flexible backings. This test method is suitable for quality control evaluations, as well as research and product claims purposes.
The test method was developed to evaluate adhesives which form a bond of measurable strength rapidly upon contact with another surface and which can be removed from that surface cleanly, that is, without leaving a residue visible to the eye. For such adhesives, often medical in nature, tack may be measured as the force required to separate an adhesive and the adherend at the interface after they have been brought into contact under a defined load of known duration at a specified temperature.
