Test Principle
In the determination of tack by rolling-ball method, a steel ball is released at the top of an inclined trough, the allowed to accelerate down and roll on to a horizontal surface covered with a pressure-sensitive adhesive. Tack is determined by measuring the distance that the steel ball travels across the adhesive before stopping.
Test Standards
GB/T 4825 (Method B: Inclined Trough Rolling Ball Method), PSTC-6, ASTM D3121
| Basic Applications | Applicable to tack test of pressure-sensitive tapes and similar pressure-sensitive adhesives with inclined trough rolling ball method |
The instrument is designed according to the inclined trough rolling ball method and can be used for tack determination of specimens The structure and steel balls of the instrument are designed according to national standards, which guarantees the accuracy of test data
