Types of Paint Testing And Coating Testing

Manufactures need to ensure that a comprehensive paint and coating test is conducted to get their product quality certified. These qualitative and quantitative tests conducted help the specialists to overcome the toughest challenges in the paint and coating industry. Experts at paint testing labs use a wide range of paint and coating tests like failure analysis, adhesion strength, and chemical resistance are important to analyze the performance of a paint designed for specific industrial and residential uses. Below is a full range of paint testing and coating services that paint industries must use to test the quality of their paints. 1. Abrasion Resistance One of the most common tests to evaluate the quality of paint coatings is the Abrasion resistance test. This test is performed to determine the ability of the paint coating to resist deterioration caused by mechanical wear and tear when applied to rigid surfaces like metal or glass panel. Surface modifying additives are often added to enhance the abrasion resistance in paints. This test is one of the best ways to determine the robustness of a paint's coating. 2. Adhesion Test It is a quantitative test conducted to determine whether a coating will adhere to the surface properly or not. This test is usually conducted using a pull-off knife or a loading fixture. Once the testing has been conducted, polyetheramine the results help you determine if the cause of failure was adhesive or cohesive. 3. Alkali Resistance Test This test is generally performed on paints and lacquers used in bathrooms, kitchen and laundries to check the extent to which a paint can resist or withstand any chemical reaction with an alkaline substance such as cement, plaster, limestone, soap, etc. 4. Cass Test Not only is this testing applied to determine the corrosive performance of copper/ nickel/chromium decorative coatings, but it also helps to evaluate paints on steel. This test can also help determine corrosion resistance of various aluminum alloys. 5. Chemical Resistance This test helps you rule the ability of a coating to resist staining and deterioration caused by chemical substances. 6. Chip Resistance This test helps you evaluate the ability of surface coating to resist chipping caused by the impact of gravel or flying objects. 7. Coating Hardness Paint testing labs administer this test to determine the hardness of a paint coat using this test. This test also indicate the durability of a a coating. 8. Coating Surface Roughness or Profile This test helps you determine the profile or surface roughness which is critical for proper and effective preparation of surface before coating. The adhesive properties of coating is reduced if the profile is too low. If the profile is too high, the profile peaks remain uncoated. 9. Coating Thickness With the help of this testing, you can determine the thickness of a coating, paint plating, or a galvanized surface. This test uses handheld or stationary micrometers to measure the film thickness of dried films of paint, varnish, lacquer, and related products. 10. Condensing Humidity This test is performed to determine the water resistant properties of an organic coating using the process of controlled condensation in paint testing labs where one side of the sample is exposed to heated, saturated mixture of water and air while the other side is cooled at room temperature. 11. Crosshatch Adherence In case you want to determine the adhesion of a large variety of coatings, this test is recommended. 12. Cyclic Corrosion This test is specified to evaluate the corrosion degradation curves of paints or coats used on steel bridges. 13. Drying Time Different paints have different drying time. This testing is performed to determine the time taken by a coating to totally dry and cure. While it only takes a few hours for a certain kind of coating to dry, it may take days or even a week for the solid components to adhere with each other. Based on the testing results, the manufacturers can use the right paint or coat for their products. 14. Failure Analysis This test determines when, where, and how the failure of paint can occur. Paint testing labs use state of the art equipment to testing and determine failure points in paints and coatings. 15. Falling Weight This is a systematic testing used to screen the coating material in pipes and check if they can resist the physical damage caused during shipping, handling, or installation. Spectro Analytical Labs With this detailed list of tests and several others, certified paint testing labs are able to produce comprehensive analysis of a wide variety of paints and coats used in various manufacturing industries. Thanks to these tests, your products will be on par with those in the international market.
