What is rolling ball tack test method?

Understanding the Rolling Ball Tack Tester and Its Functionality

The rolling ball tack test method, widely recognized for its efficiency, gauges the adhesive properties of materials, specifically pressure-sensitive adhesives. This method evaluates how well a material can stick to a surface with minimal pressure applied. For those seeking reliable equipment to measure adhesive tack, the Presto rolling ball tack tester stands out as a premier choice, allowing for swift assessment of adhesive behavior.

In this blog post, we will delve into the specifics of this remarkable lab testing equipment and clarify its operational principles. Let's dive in.

Overview of the Rolling Ball Tack Tester

Adhesive materials are extensively used across multiple sectors, particularly in packaging, including food and pharmaceuticals. The bonding speed between two surfaces directly correlates with the adhesive's tack. The rolling ball tack tester serves as an efficient tool to assess an adhesive's rapid adherence to other surfaces. 

This laboratory instrument employs a rolling ball technique to determine the primary adhesive properties of adhesive tapes by observing the effect on adhesion immediately following the collision of the rolling ball and adhesive specimen. A steel ball rolls down a predetermined incline on a grooved path until reaching the base of the test platform. For more on how to operate a rolling ball tack tester effectively, please read the relevant documentation.

Operating Principle of the Rolling Ball Tack Tester

The rolling ball tack tester operates on a fundamental principle where a steel ball is released from a predetermined height on a slope. The incline angle is fixed to the base of the test platform. Below this incline, the pressure-sensitive tape is secured. As the ball rolls down, it achieves maximum speed at impact, traversing the tacky surface, which slows its motion due to the adhesive’s resistance until it comes to a stop. A shorter travel distance indicates a greater tackiness level of the adhesive.

Before conducting the tests using this laboratory equipment, ensure the surface is clean, then adhere the sample properly. The adhesive side of the tape should be facing upward. Insert the SS ball into the designated area and elevate the knob, releasing the ball over the sample. By measuring the distance the ball travels with respect to the T on a steel scale, you can assess the tackiness with ease.

General Testing Procedures

• Begin by cleaning the inclined trough and ball thoroughly using n-heptane or methyl alcohol.
• Avoid touching the cleaned surfaces with fingers afterwards.
• Cut a sample measuring 15" long (380mm) by 2" wide (50mm) for testing.
• Align the test specimen adhesive side up with the trough, securing it at both ends with weights.
• Ensure the device is level and in alignment with the trough axis. 
• Using a lint-free cloth, position the ball at the top of the inclined trough for testing. 
• Press the spring lever to allow the ball to descend the trough.
• Measure the distance from the base of the incline to where the ball concludes its motion.
