Conical Mandrel Tester

The varying mandrel diameter (3.2 mm – 38.1 mm) stretches a coating

through a gradient of distension, allowing precise determination of adhesion characteristics.

  • Panels up to 20 cm and 1.6 mm thickness can be tested
  • Durable sturdy stainless steel mandrel

Conical Mandrel Tester

The varying mandrel diameter (3.2 mm – 38.1 mm) stretches a coating

through a gradient of distension, allowing precise determination of adhesion characteristics. 

  • Panels up to 20 cm and 1.6 mm thickness can be tested
  • Durable sturdy stainless steel mandrel

Procedure

– Cover test panel with paper between mandrel and draw bar and clamp the probe.

– Fold the panel around the cone by using the manually operated arm.

– Bend uniformly at 180 degrees within 15 seconds.

– Remove panel and examine the coating for cracks.

– Mark the point at which the cracking stops.

– Measure the distance from the farthest end of the crack to the small end of the mandrel.
