General Test Methods
- Clean the inclined trough and ball with n-heptane or methyl alcohol.
- Do not touch the trough or ball with fingers after cleaning.
- Cut a 15" long (380mm) by 2" wide (50mm) specimen for testing purposes.
- Arrange the test specimen at the end of the device, adhesive side up, in a straight line with the trough. The bottom of the device should hold downthe leading end of the specimen and a weight or other tape should hold the other end securely.
- Ensure the device is level and aligned with the trough axis.
- Use a lint free cloth to place the ball at the top of the inclined trough for testing.
- Press the spring lever and allow the ball to roll down the trough.
- Measure the distance between the end of the incline and the point where the ball stops.
Fast and economical, the Rolling Ball Tack tester provides an easy method of testing the tack of an adhesive. It quantifies the ability of an adhesive to quickly adhere to another surface. The Rolling Ball Tack tester meets the standards set by the Pressure Sensitive Tape Council (PSTC-6) for tack testing a pressure sensitive adhesive.
