Air: atmospheric corrosivity
Ground: buried corrosivity
Water: immersed corrosivity
In the atmospheric environment we distinguish some corrosion category classes according NEN-ISO 12944-5.
The example systems on this page are drafted with the following pretreatments of the substrate:
Thorough removal of grease and dirt. Surface must be clean and dry. Blast clean to Sa 2½ according ISO 8501-1:2007.
Before using the Monopox (LG) Micro Zink the following pretreatment must be applied:
Blasting according to the ISO norm 8501-1:1988 Sa 2½. Roughness profile Ra 10-12 µm Rz 50-60 µm. Surface must be clean and dry.
Pretreatment of hot dip galvanised steel:
Blast with a fine, non-metallic blasting medium until a level roughened surface is obtained, or degrease the surface and then phosphatize or chromatize (according to the rules of the manufacturer).

|Our example coating systems are based on the quality standard NEN-ISO 12944:5. In many cases there are specific demands by a contracting party and/or applicator. Please contact our technical department for a tailor made advice. Support about atmospheric conditions is also a service we provide. The map located on the right shows the atmospheric categories in the Benelux.
