adhesive holding power testing

Introduction: Adhesive holding power testing becomes easier to interpret when load, time, fixtures, temperature, humidity, and failure are read as one measurement chain. For test engineers working with pressure-sensitive tapes, labels, medical patches, or protective films, holding power is not the same as instant tack or peel adhesion. The core question is whether a bonded sample can resist sustained shear stress under defined conditions. A holding power tester or SAFT test chamber helps turn that question into an observable result: how long the adhesive assembly remains attached before slipping or falling. This article explains the measurement variables behind that result,…
