CuO (Bromosphaerol) and CeMo (8 Hydroxyquinoline) microcontainers incorporated into commercial marine paints

Abstract

AbstractWe developed CuO and CeMo microcontainers, which were filled with Bromosphaerol (CuO (BR)), Sea‐Nine 211 (CuO (SN)) and 8‐Hydroxyquinoline (CeMo (8‐HQ)). We created coatings on metals using the basic resins we took from the WILKENS and Re‐Turn companies without additives of the companies. The coatings were studied in the laboratory after exposure to marine environment in Mikrolimano harbor in a distance of 12 km southwest from the city of Piraeus in the east coast of the Saronic Gulf (WILKENS) and Singapore harbor (Re‐Turn). Laboratory measurements showed that CeMo (8‐HQ) coatings exhibit better anticorrosion stability of paints in sea water than commercial paints. With regard to the incorporation of CuO (BR) into commercial paints, the results showed a drastic improvement in antifouling behavior from that resulting from commercial paints. The contact angle with water is improved by Θ = 70° to Θ = 115° possible through morphology of the surface due to the effect of the incorporation of microcontainers ensuring a better cruising behavior of the ship. This entails a dramatic rise in cruising speed, reducing fuel consumption and reducing air pollution. The technology was tested by the partial painting of two ships with our technology, one ship which traveled for a year in the Adriatic Sea (Sea Anemos) and the other traveled over a year in the Nord Sea (Berge Arzew).
