The marine cranes are designed to be operated in a high humidity and high salty marine environment, so choosing a right paint that provides effective corrosion protection is crucial. Based on Haoyo's experience, the paint system applied to the marine cranes must be complies with ISO 12944-5 C5-M. A typical Haoyo's paint system including, the primer coat use the zinc-base epoxy primers normally 40 microns, the intermediate coat use high-build epoxy coatings, approx 250 microns, the finish coat use polyurethane coatings approx 50 microns, the total dry film should be approx 340 microns. By choosing the right paint for the marine cranes that are designed for long-term wear and tear in marine environments.
