It is assumed that coating removal occurs when the tensile force generated along the latter interface, which is a function of the rheological properties of the backing and adhesive layer materials, is 3359-2 than the bond strength at the coating-substrate interface or cohesive strength of the coating.
Common methods which approach the direct tests are peel, lapshear, and tensile tests. Although some rather brittle coatings may exhibit cohesive failure, the tape test adhesion method does not make provision for giving failure locality 7, 8.

When making the incisions, use the straightedge and cut through the coating to the substrate in one steady motion. A given lot may surpass these standards and thus be suitable for general market distribution; however, such a lot may be a source of serious and unexpected error in assessing adhesion.
Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. To ensure good contact with the?

After drying or testing the coating, conduct the tape test at room temperature as de? One supplier that has assisted in the re?
After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating. There generally is difficulty, however, in relating these tests to basic adhesion phenomena.
For multicoat systems sstm adhesion failure may occur between or within coats, the adhesion of the coating system to the substrate is not determined.
Because of the variability in adhesion strength from batch-to-batch and 33359-02 time, it is essential that tape from the same batch be used when tests are to be run in different laboratories. In its simplest version a piece of adhesive tape is pressed against the paint?
After immersion, clean and wipe the surface with an appropriate solvent which will not harm the integrity of the coating.
Cohesive failure within the coating? The central issues are that the test on plastics lacks reproducibility and does not relate to the intended application.
Apparatus and Materials 5. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. These test methods were designed for relatively ductile coatings applied to metal substrates, not for coatings often brittle applied to plastic parts 7. NOTE 4—Coatings should be applied in accordance with Practice Dor as agreed upon between the purchaser and the seller.
NOTE 5—If desired or speci? Precision and Bias 8 For tests in the? Direct tests include the Hesiometer and the Adherometer 2. Major limitations of the tape test are its low sensitivity, applicability only to coatings of relatively low bond strengths, and non-determination of adhesion to the substrate where failure occurs within a single coat, as when testing primers alone, or within or between coats in multicoat systems.
