The conical mandrel bend tester is used to determine properties of a coating. Resistance to cracking detachment from its substrate and its elongation during the test. Conical mandrel test is also known as standard method for assessing the flexibility and the adhesion properties of coatings when these are subjected to bending stresses This is accomplished by bending the test material around a conically shaped metal bar. The conical mandrel bending test is a commonly used for testing for painted or coated panels. Conical Mandrel Bend Tester is widely recommended to test the resistance of a paint, coating, varnish to evaluate cracking or detachment from a metal panel. It is suitable for use with metal panels up to 0.8mm thick (flexible substrates up to 5mm thickness) e.g. polythenes or synthetic rubber. The apparatus consists of a steel mandrel 203mm in length and tapering from 38mm to 3mm in diameter. It will accommodate test panels up to 19cm x 11cm in size. A graduated scale on the clamping bar indicates the mandrel diameter at which failure has occurred. When this diameter is added to the thickness of the panel used, the percentage elongation can be calculated. Conical mandrel detects common failures of coating shows cracking or flaking after bending.
