An electronically .The PosiTest AT-A Automatic Adhesion Tester boasts an electronically controlled hydraulic pump which automatically applies smooth and continuous pull-off pressure with a user .PosiTest AT series of pull-off adhesion testers enable an operator to accurately measure the bond strength of most types of coating applied to a rigid substrate.
When higher pull-off strengths are required, the PosiTest AT can be used with custom sized dollies to attain higher pull-off strengths.For example, a 14 mm dolly provides double the pull-off strength of a 20 mm dolly. With 14 mm dollies the .An adhesion tester measures the force required to detach a coating from a substrate. Often called a pull-off adhesion tester or peel tester, an adhesion tester applies a large amount of force to evaluate a coating's bond strength. .Adhesion testing after the coating process will quantify the strength of the bond between substrate and coating, or between different coating layers or the cohesive strength of some substrates. Routine adhesion tests are used as part of inspection and maintenance procedures to help detect potential coating failures.Basics of Conducting Adhesion Testing INTRODUCTION It is important to determine the quality of the bond between materials prior to any application of new materials. A field adhesion test is a basic screening procedure that helps determine the acceptability of an existing finished surface for application of new coatings, finishes or adhered systems.
Universal testing machine for bond test. A Universal Testing Machine (UTM), also known as a universal tester, materials testing machine, or tensile testing machine, is a crucial piece of equipment in the field of material science and engineering. It’s versatile enough to perform various types of mechanical tests, including Bond test. Below are the essential parts and components .

This may be used to compare the shear adhesion of a tape to a
The Elcometer 510 Automatic Pull-Off Adhesion Tester accurately measures the strength of the bond between the coating and the substrate. Hand-held and waterproof rugged design. Intuitive & easy to use menu structure in multiple languages. Pull Off Adhesion is a simple to use, quantitative range giving a definitive adhesion value, ideal for the .The tensile pull-off method for adhesion testing, as outlined in ASTM D 4541 and similarly in BS EN ISO 4624, involves gluing a test dolly to the coated surface and then pulling the dolly by exerting a force perpendicular to the surface in an effort to remove the dolly with the coating from the substrate. . Given the distribution of the . The present work presents the latest development of laser shock adhesion test (LASAT) technology, targeting the weak bond detection in bonded aeronautic structures. This problematic is still holding back a wider use of bonding, which could however be a significant breakthrough in the way of assembling parts.
