Conical Mandrel Bend Tester

Conical Mandrel Bend Tester

The conical mandrel bend tester is used to determine the properties of a coating. Resistance to cracking detachment from its substrate and its elongation during the test.

The conical mandrel test is also known as a 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 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)
