TPJLR 52.565 Standard Test Method for Pencil Hardness of Paint Films

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of TPJLR 52.565 testing. Coatings are usually very thin layers of material supported by a substrate. Anything placed on a substrate is a coating, this includes waxes, varnish-acrylic-enamel paints, and other types of materials coated on a substrate.

A coating applied on a hard base will naturally increase the hardness of the coating. As you can see in the picture below, the ceramic coating will form a layer on your vehicle's varnish and will help protect the surface from other external factors such as harmful UV, Pollen, bird droppings, acid rain, as well as things that damage your vehicle's paintwork.

Hardness is the resistance of a solid material to deformation when a compressive force is applied. Some materials (eg metals) are harder than others (eg plastics). Macroscopic stiffness is often characterized by strong intermolecular bonds, but the behavior of solid materials under force is much more complex; Therefore, there are different hardness measurements.

Pencil hardness measurements have been used by the coatings industry for many years to determine the hardness of clear and pigmented organic coating films. This test method has also been used to determine the cure of these coatings, especially when forced-dried using heat.
