The main applications are :
• Iron phosphate
• Zinc phosphate
• Mangan phosphat
Phosphating process is mostly applied for corrosion prevention or coating before painting process. Due to the comparatively high porosity, varnish, paint and oil can adhere better to the surface.
A faultless “pre-work” is required for an optimal coating result. This includes smooth surfaces and edges, clean welding seam, material free from cracks, blowholes, and other inclusions.
