Pressure-Sensitive Tape Initial Adhesion Tester 0 ～ 60° Inclined Rolling Ball Mode ASTM D3121-20

ST106 Initial adhesion tester

ST106 initial adhesion tester, also known as the initial adhesion tester or tape adhesion tester, is designed and manufactured in accordance with the requirements of the new version of the 2025 Chinese Pharmacopoeia "0952 Adhesion Force Determination Method". The equipment adopts the inclined rolling ball method. When a small pressure occurs between the steel ball and the adhesive surface of the test sample, the adhesive tape, label, and other products are used to test the initial adhesion of the sample to the steel ball. Suitable for conducting initial adhesion testing on pressure-sensitive tapes, medical patches, self-adhesive labels, protective films, and other related products.

The initial tack tester is suitable for conducting initial tack tests on products such as pressure-sensitive adhesive tapes and self-adhesive labels. The label initial tack tester complies with the GB/T 4852 standard "Method for Initial Tack Test of Pressure-Sensitive Adhesive Tapes—Ball Rolling Method," which employs the principle of the inclined ball rolling method. It characterizes the initial adhesion performance of adhesive products by the maximum steel ball number that can be adhered.

Testing Principles

Roll a steel ball over the adhesive tape adhesive surface placed flat on an inclined plate, and evaluate its initial viscosity based on the maximum size of the steel ball that can be adhered to by the adhesive surface of the specified length; Alternatively, a steel ball of a specified size can be rolled over an inclined groove and its initial viscosity can be evaluated by measuring its rolling distance on the adhesive surface of the adhesive tape on a horizontal plate.

Using the inclined rolling ball method, the initial adhesion of the sample is tested by the adhesive tape's adhesion to the steel ball when there is a brief contact between the adhesive surface of the steel ball and the pressure-sensitive tape under slight pressure.

Equipment features

● Using the testing principle of inclined rolling ball method, the instantaneous adhesion performance of the sample is tested.

● The test steel balls are designed completely in accordance with national standards, ensuring high accuracy of test data.

● The tilt angle of the test can be freely adjusted according to the user's needs
