Ring-Cut Method Adhesion Tester

The circle method adhesion tester uses a fixed-load stylus to draw a spiral line on the coating surface, and determines the adhesion grade based on the peeling condition of the coating. It is used to test the bonding strength between coatings, inks, etc., and substrates, with results expressed on a scale of 1 to 7, where lower numbers indicate better adhesion.

The adhesion tester employs a comparative analysis of methods including the cross-cut test, the scratch test, and the pull-off test.
This article compares three commonly used adhesion testing methods: the cross-cut test, the scratch test, and the pull-off test.
Circle method adhesion tester for evaluating the bonding strength of organic coatings
This article introduces how the circle method adhesion tester evaluates the bonding force between organic coatings and substrates. The instrument uses a stylus to draw a spiral line on the coating surface, and the adhesion level is assessed based on the number of circles before the coating begins to peel off. A smaller number indicates stronger adhesion.
Circle Method Adhesion Tester for Evaluating the Adhesion of Paint Coatings by the Circular Rolling Line Method
The rolling circle method is a technique for testing the adhesion of paint coatings using a circle-drawing instrument. The instrument employs a fixed-load stylus to draw a continuous circular trace on the coating at a constant speed, and the adhesion level is assessed based on the peeling condition of the scratch.
Operation Specification for Circular Scratch Adhesion Tester
The circle method adhesion tester is used to evaluate the adhesion strength between coatings and substrates. Before operation, it is necessary to inspect the instrument, prepare samples, and control the ambient temperature and humidity. During testing, the sample should be secured, appropriate load and scratch spacing should be selected, and the stylus should be moved at a constant speed to create a circular scratch.
Correlation of Evaluation Results Among Circle Method, Grid Method, and Pull-Off Method in Adhesion Assessment
This article mainly discusses three common methods used in coating adhesion testing: the cross-cut test, the scratch test, and the pull-off test. The choice of method should be based on the specific characteristics of the coating and the testing objectives. Sometimes, combining multiple methods can provide a more comprehensive evaluation of adhesion performance.
