When testing the adhesion of a coating at a job site, the preferred method is ASTM D3359, Test Method A - X-Cut Tape Test. This test method is used to establish whether the adhesion of a coating to a substrate is at an adequate level. In order to conduct a field test for paint adhesion, the following materials will be needed: • Cutting Tool .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.
How does pull-off adhesion testing work? Pull-off adhesion testing works by applying a perpendicular tensile force to a coating and substrate. Typically, a test will involve a digital or manual pull-off adhesion testing machine with a dolly. Before staring the test, both the dolly and coating need to be cleaned. The primary methods used to test paint adhesion are explained below. 1. Cross-cut test by tape test method ASTM D3359 — Standard test methods for rating adhesion by tape test This test method covers procedures to assess the adhesion of coating films to metallic substrates. This is done by applying and removing pressure-sensitive tape over .1.1 This test method covers a procedure for evaluating the pull-off strength (commonly referred to as adhesion) of a .

The following procedures will provide information on performing the various testing; anyone with basic knowledge and competency can perform these tests. Coating Adhesion ASTM D3359 - Standard Test Methods for Rating Adhesion by Tape Test Simply known as the “tape test”, this basic method is a screening test used to evaluate lower-Repeat the test in two other locations on each test panel. For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface. Peel Angle and Rate The standard requires that the free end of the tape be removed rapidly at as close to a 180° angle as possible.
Paints and varnishes — Pull-off test for adhesion 1 Scope This International Standard describes methods 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. These test methods have been found useful in comparing the adhesion behaviour of different coatings.PSTC-4 Adhesion to Liner of Presure-Sensitive Tapes at 180° Angle 3.

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 .The property determined by this empirical test procedure depends, among other factors, on the adhesion of the coating to either the preceding coat or the substrate. This procedure is not, however, a means of measuring adhesion. NOTE 1 Where a measurement of adhesion is required, see the method described in ISO 4624. the adhesion of the coating films to metallic substrates by applying and removing the 25 mm semi-transparentpressure sensitive tape over cuts made in the film. 6.2 Test Methods'-There are essentiallytwo test methods for the determinationof adhesion. 6.2.1 Test Method 1 - It is generally used for job at site andifthe dry film thickness is 125 .A standard method for the application and performance of the pull-off adhesion test is available in ASTM D4541—Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers and ISO 4624—Paints and Varnishes — Pull-off test for adhesion..

1.2 Test Method A is primarily intended to rate the adhesion of coatings and coating systems greater than 125 μm (5 mils) in total thickness, while Test Method B is primarily intended to rate the adhesion of coatings and coating systems less than 125 μm (5 mils) in total thickness. Test Method B is not considered suitable for films thicker than 125 μm (5 mils) unless wider .In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test, and others. [1]Cross Cut TesterTest Methods. 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.
