Active seal solution to mitigate corrosion

Companies and industries affected by corrosion should consider Afrisun’s High Ratio Calcium Sulfonate Alkyd (HRCSA) coating to mitigate the threat of corrosion at production plants in the metal- and industrial sectors, says local corrosion solution provider Afrisun Coating Enterprises CEO Quentin Erasmus.           HRCSA is an “active sealant” that is compatible with concrete and a perfect duplex/overcoat for hot dip galvanising and forms a homogenous seal over concrete and metal. Passive barrier coatings are simply a film applied over the substrate separating the atmosphere from the substrate but when damaged, under-creep and corrosion will occur. However, the HRCSA coating reacts with the zinc carbonate layer on the surface of the zinc, pushing the pH > 10.1.
