Test instructions:
The electric pencil hardness tester uses the hardness pencil to scratch the surface of the coating to test the surface hardness of the coating layer. The hardness pencil is fixed at an angle of 45 °, so that the front end pen center contacts the surface of the coating layer, and appropriate load is applied. Move the test platform at a certain speed (JIS specification 0.5mm/s) to move the surface of the coating layer through the pen center, and the coating layer will not cause damage (scratch) to the softest pencil grade The hardness of the coating layer is considered.
