ACID, ALKALI AND SALINE SOLUTION STORAGE VESSELS The concept of VICOR® coatings to be used in highly aggressive media is that of multi layer compositions of special purpose materials ensuring a layer-by-layer reduction of the permeating medium aggressiveness and selective bonding of the most aggressive components by the internal coating layers. This design enhances the coating's stability and operating temperature dramatically and makes the coating less vulnerable to technological and operational defects.

Another important advantage of VICOR® coatings is their immunity to chloride deposition, which makes it possible to save on washing-over. VICOR® coating components contain no iron, lead or aluminium ions that degrade viscose yarn. VICOR® coatings provide an efficient way of repairing lead plating and rubber lining of the evaporators.
