The ISO 2 2553-14 standard is part 14 on Paints and varnish electrodeposition coatings and focuses on the deposition performance of coatings. The standard specifies the deposition behavior of electrodeposition coatings during application, including testing methods for key performance indicators such as coating uniformity, adhesion, and coating thickness. By following this standard, electrodeposition coatings can be ensured to have excellent durability and performance in a variety of application environments, especially for demanding anti-corrosion and abrasion coating applications. The application of the standard can help Coating manufacturers and related industries to improve product mass and ensure the Stability and durability of coatings in actual use.
