Putty Flexibility Testing Machine

The putty flexibility tester evaluates the crack resistance of putty coatings by bending metal test panels. During the test, one end of the panel is fixed, while the other end is pressed down at a constant speed to a specified curvature. The surface of the coating is then observed for cracks. This method is used to assess the adaptability of building putty to substrate deformation and to control the quality of interior and exterior wall plastering.
Selection
When selecting, ensure the bending shaft diameter meets standard requirements, and the stroke range covers common test arcs. The pressure rollers should be parallel and flexible, while the clamping device must be anti-slip and non-damaging to the test plate. Consider adjustable test speeds, and equip with standard test plates and deformation measurement scales. The device should have a sturdy structure, be easy to operate, and require minimal maintenance.
