Phosphating

The ideal treatment prior to corrosion protection and keying.

The wide range of phosphating processes implemented at Walter Werner provides all kinds of pretreatment variants.

The essential properties at a glance

• temperature resistant
• optimal keying for subsequent coatings enhancing corrosion resistance
• corrosion protection enhanced with oils, waxes, and emulsions
• zinc phosphate coating with good antifriction properties, e.g. for cold forming steel

With optimal processes to the ideal surface

• perfectly ideal pretreatment for wet, powder, cathodic dip painting, and bonding agent coats
• wide range of phosphating modes:
  • thin layer (trication process)
  • iron phosphate (pickling of aluminium and steel parts)
  • zinc phosphate (treatment prior to downstream coating)
  • thick layer (Ca phosphate)

• inhouse plant with drum and rack systems
