The paint film flexibility tester is also called the paint film elasticity tester, which is manufactured in accordance with the national standard GB/T1731 "Method for the determination of paint film flexibility". The test plate coated with the coating film is bent on shafts of different diameters, and the minimum shaft diameter (mm) that does not cause damage to the coating film is used to express the flexibility of the coating film.

The main technical parameters:

*Stainless steel shaft length: 35mm
*Shaft rod 1: diameter Φ15mm;
*Shaft rod 2: diameter Φ10mm;
*Shaft rod 3: diameter Φ5mm;
*Shaft rod 4: diameter Φ4mm;
*Shaft rod 5: Section 3×10mm, radius of curvature Φ1.5mm;
*Shaft rod 6: Section 2×10mm, radius of curvature Φ1.0mm;
*Shaft rod 7: Section 1×10mm, radius of curvature Φ0.5mm;
*The thickness of the bottom plate of the test plate: 0.2-0.3 (tinplate)
*Dimensions: 305×75×90
