What is the film hardness
The hardness of the powder paint film refers to the resistance of the paint film after drying has a solid, i.e. the film surface the role another on the greater hardness of the material performance.
This resistance exhibited by the film can be provided by a certain weight of the load acts on the relatively small contact area, by measuring the ability of the film antideformation manifested, so the film hardness is a view showing one of the important properties of the film mechanical strength.
Film hardness can reduce the degree of friction or collision damage.
