The varying mandrel diameter (3.2mm- 38.1mm) stretches a coating through a gradient of distension, allowing precise determination of adhesion characteristics.

Panels up to 20.3cm and 1.6mm thickness can be tested.

Durable sturdy stainless steel mandrel.

Procedure

•Carefully cover test panel with paper between mandrel and draw bar and clamp the probe.

•Fold the test panel around the cone by using the manually operated arm that is pivoted at the ends of the axis of the cone.

•Bend uniformly at 180° within 15 seconds.

•Remove panel and examine the coating for cracks.

•Mark the point at which the cracking stops and measure the distance from the farthest end of the crack to the small end of the mandrel.

•Appropriate calibration curves also permit determination of the elongation values of the paint film.
