About This Product
The pencil hardness test is a simple way to compare the hardness of a paint or coating film. Pencils of known grade are drawn across the coating, and the coating's resistance to deformation is judged from the pencil grades. A three-point contact frame keeps the pencil at a fixed 45° angle so that each scratch is made the same way. The tester is used on coated sheet and can be taken from the lab to a construction site.
