Conical Mandrel Bend Tester

The company makes available high quality Conical Mandrel Bend Tester. The range of Conical Mandrel Bend Tester made available by us is used to determine properties of a coating. Conical Mandrel Bend Tester is instilled with resistance to cracking detachment from its substrate and its elongation during the test. Conical Mandrel Bend Tester is also known as standard method for assessing the flexibility and the adhesion properties of coatings when these are subjected to bending stresses.

Conical Mandrel Bend Tester is made use of in testing the resistance of a paint, coating, and varnish to evaluate cracking or detachment from a metal panel. Conical Mandrel Bend Tester is suitable for use with metal panels up to 0.8mm thick (flexible substrates up to 5mm thickness) e.g. polyethene or synthetic rubber.

Apparatus

• The apparatus of Conical Mandrel Bend Tester 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
• Can be used in accordance with DIN ISO EN 6860, ASTM D 522, BS 3900 E11, and DIN 53150
