Ship Hull Protection

<Ship Hull Protection</b> The underwater hull and the surface hull are not only painted for visual reasons. The painting or the coating prevents the electrolyte water and oxygen from touching metal. Metallic zinc is often found in the synthetic resin-based paints. In this way, both protection principles are combined: active protection through cathodic corrosion protection and passive corrosion protection through barriers for water and oxygen.
