What is special about marine paints?
Vessels operate in seawater. So some surfaces of the vessel are exposed to seawater constantly, whereas some surfaces are not. But these surfaces are still surrounded by the sea. Therefore, marine paints must resist salt water as well as atmospheric corrosion. What different types of marine paints are used? Three basic types of marine paints are in use. The types are as per paint composition. 1. General purpose marine paints: Alkyd resin based, Bitumen based and Gilsonite based These paints have a protection life of about five to six months and cost relatively less. After the protection period, the vessel needs repainting. 2. Chlorinated rubber based: Good resistance to salt water and atmospheric corrosion. The protection life is about two years. 3. Epoxy resin based: This type is an expensive type, but the protection life is up to five years. There are also zinc-rich paints, which are still costlier, but the performance is very high. What paint should be applied to ships? This depends
