The hardness of the coating is one of the important properties that characterize the mechanical strength of the coating. At present, pendulum hardness test methods are commonly used to determine the hardness of automotive coatings. The pendulum hardness can be divided into two types: single pendulum type and double pendulum type. The former measurement value is expressed in seconds, and the latter is expressed as a percentage of glass hardness. The single pendulum is also known as Koenig and...
