BTT Ball Tack Tester
Application
The rolling-ball tack test is fast, easy to run, and requires little investment in equipment and little operator training. This test is intended primarily for quality control use since it demonstrates good reproducibility within a single laboratory and the ability to detect batch-to-batch variations accurately if adhesive film thickness is held constant. Rolling ball tack is not intended as an investigative tool since for most pressure-sensitive adhesive applications rolling ball tack results do not correlate well with application tack requirements.
Tough Type
BTT-01 Ball Tack Tester is for the measurement of the comparative tack of pressure-sensitive adhesives by a rolling ball. It’s an inclined trough equipped with a release lever at the top through which the ball gains downhill momentum. The ball is a 7⁄16-in. (11.1-mm) diameter steel ball.
Standard
PSTC-6, ASTM D3121, JIS Z0237, GB/T 4852.
BTT-02 Inclined Type Ball Tack Tester is equipped with an inclined plate of 20°, 30° or 40° inclined angle. The inclined plate is a smooth and flat one made of aluminum.
A steel ball of various specifications is placed at the upper part of the inclined plane, followed in the lower 100mm section is the approach table, where the ball can accelerate after released. The test sample is placed below the approached table in the next 100mm.
The ball is released and stuck in the test area.
