MARINE PAINTING
The Cartubi shipyard is a leading company in the naval sector, offering high-quality marine painting services. Naval painting is a fundamental process in the construction and maintenance of ships, playing a crucial role both in terms of aesthetics and long-term durability.
The importance of painting ships and yachts
Marine painting, or coating, is a fundamental process for vessels, not only to enhance the aesthetic appearance of the ship but also to ensure its longevity and protection against weathering and wear.
Ships are exposed to a variety of adverse environmental conditions, including sea moisture, sunlight, corrosion from saltwater, and abrasion from collisions with floating objects. Marine painting is therefore essential to preserve the materials of the hull and internal structures, extending the vessel’s lifespan.
Types of coatings
In the Cartubi shipyard, various types of marine coatings are carried out to meet the specific needs of the vessels. These include:
- Brush or spray painting: one of the most traditional methods of painting, where liquid paint is applied directly to the surface of the ship using brushes or spray guns. This method offers greater flexibility in the choice of materials and finishes but may require more time and labor compared to powder coating.
- Powder coating: it’s a protective coating process used to shield the surface of ships from corrosion and weathering. This painting method is similar to powder coating used in other industries but is tailored to the specific needs of ships and marine structures, ensuring a high level of durability over time.
- Epoxy coatings: Epoxy coatings are known for their corrosion resistance and are often used to protect the metal surfaces of ships. These coatings contain epoxy resins that harden when mixed with a hardening agent. They can be applied both in liquid form and as powder paint.
- Hot-dip galvanizing: Hot-dip galvanizing is a process in which the metal surface of the ship is immersed in molten zinc. The layer of zinc applied protects the surface from corrosion by sacrificing itself for the underlying metal. This method is particularly effective for metal parts submerged in seawater.
- Anti-fouling coatings: These coatings are designed to prevent the accumulation of marine organisms (such as algae and barnacles) on the hull surface. They are formulated to reduce friction and improve maritime transportation efficiency. Some of these coatings contain chemicals to prevent marine organisms attaching, while others use physical methods to discourage organism attachment.
- Polyurethane coatings: Polyurethane coatings are known for their durability and resistance to weathering. They are often used for surfaces exposed to aggressive marine environments, such as ship superstructures.
