The Pull – Off adhesion testers are fully portable and provide accurate numerical value for coating adhesion. Pull – off adhesion testing is widely used to assess the protective coating process and to determine if a coating is fit for service in new construction and for repairs to existing structures. 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.
Measures adhesion of coatings to metal, woo concrete and other rigid substrates Revolutionary self-alignment. The force required to pull the stud from the surface, together with the . The pull – off strength of a coating is a performance property that may be referenced in specifications.
The pull – off adhesion strength and mode of failure of a coating from a concrete substrate are important performance properties that are used in specifications. This test method is applicable to any portable apparatus meeting the requirements for . Variations in strength. The PosiTest Adhesion Tester measures the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure. This measured pull – off force provides a direct indication of the strength of adhesion between the coating and the substrate. By eliminating sources of pull – off variation, such as unintended bond failures between the adhesive and poorly prepared dollies, adhesion test become even more meaningful and predictable.
Pull – off or pull-out testing involves the separation of two secured parts under tension. This may be to test the strength of crimped or welded wire terminals, the strength and integrity of adhesives and coatings ( adhesion and cohesion within the layer), industrial fixings and fasteners, stoppers, lids and . Pull Off test to evaluate the compressive strength of concrete: an alternative to Brazilian standard techniques.

Humboldt provides pull – off testers for concrete bond strength testing as part of a complete line of materials testing equipment. 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. It is most useful in providing relative . During the testing a metal dolly is glued to a pipeline coating then pulled off, to assess adhesion of the coating. In practice, are very sensitive to circumstances and have large standard . Many translated example sentences containing pull off test – Russian-English dictionary and search engine for Russian translations.
Several standards frame the application of this test and interpretation of its. The pull – off test is a very popular way of evaluating the adhesion strength of renderings or ceramic tiles. In our laboratory, the in situ pull – off test is frequently applied to support the diagnosis of causes fo.
