ST106 Initial Adhesion Tester for Adhesion Force Determination of Protective Films and Pressure Sensitive Adhesive Tape

ST106 Initial Adhesion Tester Introduction
The ST106 Initial Adhesion Tester is professionally applied to measure the initial adhesion of protective films and pressure-sensitive adhesive tapes. Manufactured in strict compliance with the 2020 edition of Chinese Pharmacopoeia <0952 Adhesion Force Determination Method> and the national standard GB/T 4852 Test Method for Initial Adhesion of Pressure Sensitive Adhesive Tape - Rolling Ball Method, this instrument adopts the inclined rolling ball testing principle.
During testing, a steel ball rolls down the inclined track and makes slight contact with the adhesive surface of the test sample. The initial adhesion performance of samples such as adhesive tapes and self-adhesive labels is evaluated and determined based on the bonding condition between the steel ball and the sample surface.
This tester is widely suitable for the initial adhesion testing of various products, including pressure-sensitive tapes, medical patches, self-adhesive labels, protective films and other adhesive-related products. It characterizes the initial adhesion performance of adhesive products by testing the maximum specification of steel balls that can be stably adhered to the sample surface, delivering accurate and repeatable test results.

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
