This machine applies force to the specimen using pressure plates. The specimen is damaged through the rubbing action of the pressure plates, thereby testing the shear flexing resistance of the specimen’s coating. It is suitable for materials with adhesive surfaces or materials with a thin polyurethane coating applied to a rough surface.
1.Instrument Introduction
This machine applies force to the specimen using pressure plates. The specimen is damaged through the rubbing action of the pressure plates, thereby testing the shear flexing resistance of the specimen’s coating. It is suitable for materials with adhesive surfaces or materials with a thin polyurethane coating applied to a rough surface.
2.Main Functions
Suitable for testing the flexing resistance of polyurethane-coated materials, etc. Two methods are available: pressure method and non-pressure method.
