Paint Hardness Testing

The Need for Paint Testing

Paint hardness is the result of a chemical reaction between paint and the substrate it adheres to. Paint must be hard enough to protect the surface it is applied to against abrasion of media. The thickness of the paint, type of paint, nature of the substrate and temperature and humidity of the surrounding all play a role in influencing the hardness of the paint. Applied Technical Services performs paint hardness testing to help clients determine the effectiveness of their coatings.

Paint hardness testing can be useful in rating its resiliency to scraping, polishing, scratching, gouging, rubbing, and other external abrasive forces. Companies need to know the hardness of their coatings in order to determine whether it is appropriate for their intended application. ATS’ environmental testing lab has the necessary tools and technology to help companies accurately evaluate paint hardness. Our testing services deliver clear data with quick and concise results.

Pencil Hardness Test
The Pencil Hardness Test is one of the most popular testing method in the paint industry. The procedure consists of using pencils of increasing hardness to make marks at a 45-degree angle on a coated panel until the pencil that will not damage the coating is determined.
