WebThe definition of tack is the property of a pressure sensitive adhesive that allows it to adhere to a surface under very slight pressure. It is determined by the ability of the adhesive to quickly wet the surface it contacts. There are four standard test methods that are used globally to evaluate a pressure sensitive hot melt’s tack. WebThe distinction between tack and peel is the contact time as defined by the above definition. Consequently, the test must be designed that the tack probe makes contact with the adhesive for a very short time. In contrast, peel tests require that the adhesive be in contact with the substrate for a long period of time.

WebThe fundamental tests would ordinarily consist of peel adhesion tests, shear holding power tests, and one or more tack tests. Often these adhesion tests will be carried out on 25.4 mm (1.0 inch) wide tapes prepared by accurately coating a 0.025-0.050 mm thick adhesive (dry) on a standard backing, such as a 0.025-0.050 mm thick polyester film. WebThe adhesion performance of pressure sensitive adhesives (PSAs) is determined by three properties: tack, peel strength (adhesion) and shear strength (cohesion). Tack is a dominant property of PSAs and is defined as the ability to adhere to any surface under low (1–10 Pa) contact pressure and short (1–5 s) cek coverage area biznet
