    Operation Steps

    Carefully cover the surface of the paint film with paper, clamp it between the conical shaft and the operating rod, and clamp the fixed plate.

    Use the manual lever to bend the test plate along the conical axis

    Bend the sample 180 degrees with uniform force within 15 seconds

    Remove the paper and check where the paint film is cracked

    Record the location of the crack and measure the distance from the crack to the smallest side of the bending shaft diameter

    The extension value of the paint film can be judged in the calibration curve
