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.
