Three major pressure sensitive adhesion performances are determined and reported for all hot melt pressure sensitive adhesives (HMPSAs). They are peel (typically 180°-peel), tack, and shear (or holding power). Sometimes, the heat resistance, Shear Adhesion Fail Temperature (SAFT), and cold resistance are also requested for specific applications. These standard test methods are available form ASTM, PSTC, TLMI, FINAT, and AFREA, etc. Although most lab technicians may follow test procedures according to those test methods… Read Article >>
