Rolling Ball Tack Tester

The Rolling Ball Tack test helps to test the tack of any adhesive. The instrument is very easy to operate and very economical too. It measures the ability of an adhesive that rapidly adhere to another surface. The tester complies with various standard test methods provided by various standardization authorities to perform the tack test on a pressure sensitive adhesive.This lab testing equipment has been designed with high-quality industrial standards that include ASTM D3121-94.

In this type of test, a steel ball is permitted to roll down from a particular starting point in the grooved path which tends at a particular angle to the bottom of the test platform. The responsive pressure tape is affixed below the end of the path of the platform. The roll back attains maximum speed when moving down and roll on the tacky surface. The shorter the distance covered by the ball, the higher will be the tackiness of the adhesive and vice versa.
