Deformation resistance - Elasticity

Commonly used tests used in the paint and coatings industry are: 

    • Bend test
      With this system a coated test panel or lacquered sheet metal is bent over a defined mandrel. Cylindrical mandrels in different diameters or conical mandrels are used. 
      The smaller the diameter the sharper the forming of the test panel which leads to elongation of the...

Commonly used tests used in the paint and coatings industry are: 

    • Bend test
      With this system a coated test panel or lacquered sheet metal is bent over a defined mandrel. Cylindrical mandrels in different diameters or conical mandrels are used. 
      The smaller the diameter the sharper the forming of the test panel which leads to elongation of the panel including the coating. A sharper deforming causes more stress to the coating which may lead to cracks or adhesion failure. 
      Cylindrical bend test are recognised to be more precise in comparison to conical bend tests which have the advantage that a range of mandrel diameters can be checked on just one panel.
    • Impact Test, or tubular impact test
      With an impact test a rapid deformation of a painted test panel is generated. A specified weight with a specified punch is dropped on a test panel from different heights. The damage on the sample is observed after the test and provides information about physical properties of the coating such as elasticity, hardness and adhesion. 

      For the paint industry there are different tests according ISO 6272 , ASTM D2794 and others. Each standard has its own specifics such as weight, punch shape, direct or indirect impact etc..
  • Cupping test 
    Cupping testers generate, in contradiction to impact testers, a gradual deformation of the sample. An indenter with a specified shape is slowly forced through the test panel under standardised conditions. During the deformation the panel is visually observed. The cupping value of a coating is the deformation point at which the coating starts to crack. 
    To perform this test correctly it is of utmost importance that the deformation is made gradually without any interruptions.

  • The TQC Impact Test is used to determine the impact resistivity and flexibility of coatings. The dual scale instrument is equipped with a special guidance which assures that the distance between each impact is always according to the standard. For correct positioning a spirit-level is built-in. Each Impact test comes as a complete set (instrument and...

  • The TQC Automatic Cupping Tester allows to perform a cupping (Erichsen / Dent) test on coated steel panels to define the resistance of paint, varnish or related products to cracking and/or detachment from a metal substrate when subjected to gradual deformation by indentation under standard conditions.

  • The TQC Bend Test Conical Mandrel "Pro" is a laboratory apparatus to bend coated test panels over a conical shaped mandrel in order to assess the elasticity or resistance of a coating-, paint or varnish to cracking, elongation and/or detachment from a metal test panel in accordance with ISO 6860 and ASTM D522. The conical shape of the bending area allows...

  • The TQC Cylindrical Bend Test is used to determine the elasticity adhesion and elongation of paint on sheet metal in accordance with ISO 1519. A test panel (max. size 150 x 100 mm) is bent over a cylindrical mandrel. The smaller the diameter of the mandrel, the larger the tension on the coating. The test panel is then checked for cracks or damage in the...

  • Revolutionary apparatus for testing the resistivity of coatings at various stages of deformation in accordance with ISO 1520. The built in gear-box minimizes the manual force which is required to deform the test panel, allowing to perform a smooth deformation. The degree or deformation is digitally displayed at a resolution of 0.01 mm.
