The functions of marine coatings
1. Hull anti-corrosion
Ships are often subjected to environmental erosion such as salt water, ultraviolet radiation, and marine organisms, so anti-corrosion of the hull is the most basic requirement. Marine coatings can provide effective anti-corrosion protection for the hull, enhance its durability, and reduce the frequency of hull repairs, thus reducing the costs of maintenance.
2. Anti fouling and anti biological attachment
When a ship is sailing in sea, it will encounter invasion from meiofauna such as seaweed and shells, which will attach to the surface of the hull and pollute it. Ship coatings can form a smooth and hard surface, preventing these organisms from adhering to the surface, thereby reducing the frequency of cleaning and lowering maintenance costs
3. Improve navigation efficiency
The marine environment is highly suitable for the growth of microorganisms and marine organisms. These organisms attached to the hull will generate friction and resistance, and even cause damage to the ship. Ship coatings can inhibit biological adhesion, reduce friction underwater, and improve ship operating speed and navigation efficiency.
4. Beautify the appearance
For commercial ships, the appearance of the hull has always been an important factor in marketing. Marine coatings have various colors, which can meet the needs of different ships and make them more attractive during navigation.
5. Special functions
To meet special needs such as hiding from radar detection(stealth coatings) and high-temperature capability(heat-resistant coatings).
In general, Marine coatings play important roles to a ship. It can not only provide a beautiful appearance for the ship, but also has many functions such as anti-corrosion, anti-fouling, anti-biological adhesion and so on. When choosing Marine coatings, the most suitable coatings should be selected according to some factors such as the sailing environment and hull quality to ensure the durability and efficiency of the vessel.
