Paint Film Bending Tester Enamelled Cylindrical Mandrel Bend Tester for Testing Paints Varnishes Coating Flexibility QTY-32

This unit is a special instrument to evaluate the cracking resistance or peeling off from metal plate when the coating of color paint and related products is bent around the cylinder shaft under standard conditions. Working principle: Insert the test plate between the tie rod and the conical shaft, and clamp the lever with a splint, turn the shaft from front to back (to bend the test plate around the conical shaft), and measure it according to the crack position of the coating on the test plate its peeling properties. Parameters: Material: stainless steel + iron Test plate substrate thickness: ≤ 0.03inch (0.8mm) Shaft rod size Shaft small end diameter: 0.1inch (3.2mm) Shaft rod size Shaft big end diameter: 1.5inch (38mm) Taper shaft length: 8inch (203mm) Size:11*5.5*12.4 inch (280*140*315mm)Package Including1*Paint Film Bending Tester

• 【Parameter】The diameters of the paint film bending tester are 2, 3, 4, 5, 6, 8, 10, 12, 16, 18.20, 25, and 32 mm respectively. This machine is suitable for the template of thickness below 1.0mm.
• 【Working Principle】The extension properties of different coating films to substrate are also different. It can be used as a simple Pass/Fail test at a known diameter, or as a Paint of Failure test, by using successively smaller mandrels until cracking is observed.
• 【Widespread Use】Paint film bending tester mainly uses and measures the flexibility of the coating film of color paint varnish, which is one of the main indexes to measure the performance of the coating, and the choice of coating varieties. It should be of great reference value.
• 【Operating Steps】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.Bend uniformly at 180°within 15 seconds, examine the coating for cracks.
• Package included: 1 x Paint Film Bending Tester
