Features

Cylindrical mandrel testers evaluate a coating’s flexibility in regards to bending properties. A coated sheet metal is bent over a defined radius to evaluate elongation / adhesion as well as resistance to cracking.
The test procedure for elongation check is performed with fast speed (1s), while cracking is evaluated with slow speed (15 sec). The smaller the bend radius, the greater the material flexibility.
They are used in QC for simple Pass/Fail check or in R&D to determine the smallest mandrel size.

Two models are available:

Hand Bend Tester, a low cost solution with simple hand operation for Pass/Fail test according to ASTM D522.
Lever Bend Tester with operation using a lever for Pass/Fail test according to ISO 1519.

Procedure

Apply the paint film on sheet metal strips
Coat and dry film carefully to ensure reproducible results
For testing, uniformly bend the coated samples over the bending mandrels within 1-2 sec at 180 degrees
Starting with the largest bending radius, the test is continued until reaching the bending radius at which the film shows cracks
