One of the ways to test protective coatings on substrates and steel is with a pull-off adhesion test. With a pull-off adhesion tester, you can easily understand and evaluate the coating process and determine if the coating is ideal for the application, such as repairs or a new construction. The results are critical to the rejection or acceptance of the coating process where the adhesion value, as quoted by a paint manufacturer, can become adversely affected by the coating process. A low adhesion value can lead to premature failure, which is often caused by inadequate preparation of the substrate’s surface prior to coating application.
BS EN ISO 16276-1 and ASTM D4541 describe the different devices that you can use for pull-off adhesion testing. While there are traditional and manual methods to do the test, using a pull-off adhesion tester is preferred as it provides quick and accurate results. An advanced pull-off adhesion tester can measure the adhesion of the coating on rigid substrates such as concrete, wood, and metal. It uses a hydraulic pump to pull a dolly, which is glued to a substrate to record the force applied as failure occurs.
A pull-off adhesion tester is widely used in the quality assurance process in construction, as it provides a reliable and time-saving way to make sure that there is enough adhesion between the substrate and coating. The versatile tester comes in automatic and manual modes to provide more flexibility to operators and the testing requirements. In manual mode, there is a hydraulic pump that applies continuous and smooth pressure with single strokes. The pull rate indicator manually observes and adjusts the rate of pull, and the internal memory stores the maximum pull-off pressure.
An automatic pull-off adhesion tester comes with a scratch-resistant and impact-resistant colour touch screen with a keypad. Its hydraulic pump is electronically controlled to apply continuous and smooth pull-off pressure automatically, therefore, reducing user effort and error. The tester comes with a rechargeable battery that can accomplish more than 200 tests per charge, and it can still be used while charging.
