Which SSPC standard specifies surface preparation for non-ferrous metals?

SSPC-SP 16 is the standard that specifically addresses the surface preparation for non-ferrous metals. This standard provides guidelines for removing contaminants, such as oils, dirt, and old coatings, from the surfaces of non-ferrous metals to ensure adequate adhesion of subsequent coatings.

The focus on non-ferrous metals, such as aluminum and copper, is critical since these materials require different surface preparation techniques compared to ferrous metals due to their distinct physicochemical properties. SSPC-SP 16 outlines the recommended methods, which may include abrasive blasting or the use of chemical agents tailored for these materials, ensuring that the surface is clean and properly prepared to achieve optimal coating performance.

Moreover, proper surface preparation is essential in preventing future issues, such as corrosion or coating failure, thereby prolonging the lifespan of the coated structure. Understanding and applying SSPC-SP 16 helps coatings inspectors maintain high standards of quality in their work with non-ferrous metals, ensuring the effectiveness of protective coatings in various applications.
