Measure The Scratch Hardness of Paints

Measure The Scratch Hardness of Paints Using Scratch Hardness Tester

Hardness is a factor that measures the resistance level of a material to permanent or superficial damage. There are three kinds of hardness estimations, scratch hardness, indentation hardness and rebound hardness. This test measures the hardness of a sample to scratches and abrasion resulting from friction with a sharp article. It was initially designed by German mineralogist Friedrich Mohs in 1820 is still extremely popular in ranking the physical property of coated metals. It applies to various articles such as earthenware production, polymers, and covered surfaces. The property of a material that evaluates the power of the substance whether on applying pressure it gets influenced or not is called hardness. By applying a specific amount of pressure, you can see that the product completely damages or superficially damaged. By this, an individual can determine its hardness strength. Therefore, manufacturers must examine the utilization of scratch hardness tester in measuring the quality of a material.

In this test, the sample is placed on the platform and is fixed utilizing knobs so it does not move a bit during the test, or else it can create an error in the testing information. The machine has a sharp diamond pointer prepared inside. That pointer is placed on the sample and the time of test cycles, amount of rubs, and force applied is set utilizing the digital controls. The pointer begins moving in a constant sliding way over the sample trying to scratch it. If the material is not scratched it is clear and if it is scratched the material isn't clear. The machine and the test direct keep ASTM testing standards.

Scratch Hardness Tester is a high-quality device broadly used to evaluate the resistance of a material to scratch under a predetermined load. The testing instrument is utilized for a wide range of products like varnishes, lacquers, and paints.

Scratch Hardness Tester is highly suggested for the paint and plating industry and designed mainly for industrial laboratories where quality control is considered as a significant parameter and tests are conducted on the samples to determine the quality. For this sort of testing technique, a high-quality scratch tester should be utilized to measure the scratch hardness of distinct metals. It is a uniquely designed model to determine the resistance to scratch without any preparation under a predefined load. It adheres to the testing standard of ASTM. The instrument is also available with higher capacities on customer demand. It also has a digital indicator that helps to view the results in digital format.
