These tack testing fixtures can be used to measure the tack properties (instantaneous adhesion) of adhesives either through the inverted probe (ASTM D2979) or the loop (ASTM D6195) tack testing methods. It comprises: for the inverted probe technique (a flat indenter with a 5-mm diameter and annular loading weights) and for the loop (a tensile grip and a 1 inch flat base). The energy (force-displacement integral) required to completely peel out the material provides its tackiness.
- This part has a robust design and will keep its integrity for years
- Easy to assemble and mount on the tester
