These test methods cover procedures for assessing the adhesion of coating films to metallic substrates by applying and removing pressure-sensitive tape over cuts made in the film. This .Adhesion Testing. Paint. Pull-off adhesion testing is a way to help you work out how durable and lasting your coatings will be once your product is out in the real world. That’s why it’s an essential part of a solid QA process and one that’s well worth learning about.Pull-off adhesion testing is widely used to assess the protective coating process. It is also . The result is often critical to the acceptance or rejection of a coating process, as the adhesion value quoted by the paint manufacturer can be adversely affected by aspects of the coating process. Low adhesion values are indicative of premature .PosiTest CH ASTM Kit The second and most commonly used test method in the wood industry is the cross-hatch cutter test. This test is fast and simple to perform with an inexpensive cross-hatch cutter test kit, such as the PosiTest .
ISO 2409 Paint and Varnishes — Cross-cut test4 3. Summary of Test Methods 3.1 Test Method A—An X-cut is made through the film to the substrate, pressure-sensitive tape is applied over the cut and then removed, and adhesion is assessed qualitatively on the 0 to 5 scale. 3.2 Test Method B—A lattice pattern with either six or
The Paint Adhesion Test Kit, (P.A.T.), contains all of the tools and materials needed, except for the multi-tooth cutter blade, for conducting adhesion tests on paints applied to a flat, uniform surface in accordance with ASTM Test Method D3359, method B and DIN Standard No. 53151. There are two kits available: The Cross Hatch Test Kit (12596) is great for any type of flat .Types of Paint Adhesion Tests. Although there are two major types of tests (knife and pull-off adhesion tests), there are a few other types as well that are many times used depending on the surfaces and industries. Here are various types of adhesion testing methods mostly used for paints and coatings. 1- Knife Test
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 . the bond of the adhesive to the paint and paint to the wall is good. Basics of Conducting Adhesion TestingAdhesion, the measure of how well the fixative has bonded to its substrate, is evaluated through adhesion testing. This information can be used to determine the failure point of the adhesive — the least amount of duress which will cause the product .

The ATS paint testing lab, itself a part of the environmental testing division, is ISO 17025 (A2LA) accredited to perform dozens of coating analysis methods. We have a long history of providing world-class testing, inspection, and consulting engineering services to clients from an assortment of industries.An ideal field or laboratory test. Robust design; Large, non slip grip; Ideal for thin, thick or hard coatings; A quick change, 4 sided cutter allows adhesion testing on a wide range of coating thicknesses (1mm, 1.5mm, 2mm and 3mm) The Elcometer 107 Cross Hatch Cutter for adhesion testing is available as a Basic or Full Kit.Adhesion tests provide insight into the bond between a substrate and the applied coating or paint. Coating adhesions tests produce intentional coating failures that allow experts to examine the potential causes and consequences of the failure.
ASTM D3359, Standard Test Methods for Measuring Adhesion by Tape Test (Tape Test) and ASTM D6677, Standard Test Methods for Evaluating Adhesion by Knife (Knife Test) are perhaps the most widely used tests to evaluate a coatings’ adhesion to the substrate and to other coats in a multi-coat system. While tape and knife adhesion tests are .
ISO 4624:2016 specifies three methods (i.e. one dolly or two dollies on a painted panel and two dollies, one as painted substrate) for determining the adhesion by carrying out a pull-off test on a single coating or a multi-coat system of paint, varnish or related product.
ASTM D 6677 is the standard test method for evaluating adhesion by knife and contains a rating system table to evaluate the findings. No value is put on the adhesion strength of the coating; it is merely an observational rating/comparison to a pre-determined set of parameters. This test relies on the interpretation of each individual tester and .Third-party testing companies, like Applied Technical Services, Inc., will use methods like the adhesion pull test to analyze the effectiveness of your coatings. What is Adhesion, Exactly? Pull-off adhesion testing provides a qualitative . 涂层附着力测试是确保耐久性的重要质量控制措施, 通过评估涂层与基材之间的附着力来评估涂层的性能和安全性. 有助于防止涂层剥落，保证产品外观质量，同时满足行业标准和认证要求. 附着力测试对于确保涂层质量很重要, improve [.]ASTM D 3359-09e2 – Standard Test Methods for Measuring Adhesion by Tape Test ISO 2409:2013 – Paints and varnishes — Cross-cut test. . The paint has flaked partially or completely along the edges and/or some squares have .
Simple adhesion testing such as probing and attempting to lift coating with a putty knife or pocket knife is subjective. Pull-off tensile adhesion testing is conceptually simple, and it provides a single discrete quantity—the force required to cause fracture. The nature of the coating fracture in terms of adhesive vs. cohesive failure should . Paint testing reveals that about 75% of paint durability failures are related to adhesion problems. The remaining failure cases are related to discoloration or visual change such as cracking and crazing. About 90% of all these problems can be avoided by proper surface preparation before applying the paint coating. For instance, if the testing criteria is designed for 5 mils of paint application, and you only apply 2-3 mils, you could potentially alter a favorable testing result; conversely, if you apply 8, 9 or 10 mils, you could potentially create a more favorable test result. Following the proper protocol is extremely important for accurate testing .ATS offers a variety of ASTM coating adhesion testing capabilities to help clients optimize the functionality of their coating applications and avoid premature failure. Our testing services save clients money, providing them with the data necessary to pick the right coating and effectively protect their products, equipment, and infrastructure.
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 PosiTest AT can attain pull-off strengths as high as 6000 psi (40 MPa).Similarly, a 10 mm dolly provides approximately four times the pull-off .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.Providing quality control paint and coating tools and equipment for testing, measurement, and inspection for the laboratory and field since 1936. +1 (954) 946-9454.

Adhesion testing is often associated with adhesives, tape, sealants, laminates, electronics, cosmetics, medical device packaging, general packaging seal strength and applications where bond strength measurement is critical for research and quality control applications. Stud pull coating adhesion testing, for instance, is a very common test used .
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 .
