CORROSION INHIBITOR MATERIAL BASED ON PERMANGANATE SODALITE, PRIMER COMPOSITION AND COATED METAL

摘要

Sodalite is synthesized in the presence of a stoichiometric quantity of Permanganate ion. After thorough washing to remove trace salts the resulting pigment may be encapsulated with amorphous silica using the Her process. The resulting pigment has enhanced acid stability and provides excellent corrosion protection on reactive metal substrates such as Aerospace Aluminum or Coil grade Hot-Dip Galvanized Steel.
