CZY-GC Primary Adhesive Tester (PSTC-6)
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
Feature
- 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
