All industries where ferrous structures are used are exposed to both financial and environmental threats due to corrosion.
Proper surface preparation is essential before applying protective coatings to any ferrous object. Contamination can be visible but even more dangerous invisible. Invisible contamination like soluble salts have a directly relation with the formation of corrosion under protective coatings. It's important to detect the presence of soluble salts and remove them before the protective coating is applied.
Many industries have set stringent requirements for maximum allowable soluble salt concentrations for various applications. In order to test for surface cleanliness the surface contaminants must be extracted and analyzed.Download PDF Sheet
