Test instructions:
The surface hardness of the coating layer is tested by scratching the surface of the coating layer with a hardness pencil. The hardness pencil is fixed at a 45° Angle, so that the front center of the pen is in contact with the surface of the coating layer, and the appropriate load is applied. According to a certain speed (JIS specification 0.5mm/ s), the test platform is moved to make the surface of the coating layer move through the pen center.The hardness of the coating is considered to be the softest pencil grade in which the coating does not cause damage (scratches)
