Marine paints and coatings have to perform under the most difficult conditions: They must be resistant to seawater, fresh water, diesel oil and various chemicals, algae and temperature fluctuations. In addition, the semi-hard coatings are expected to exhibit gloss, richness, extreme resistance to light, weathering and abrasion.
Besides the necessary chemical requirements, the surface properties are important: For example, the surface structure of the paint has a major influence on the frictional resistance of the ship's surface when passing through waters. By wet milling to finer particle sizes, the frictional resistance can be reduced – thus reducing the energy consumption of the ship.
It is therefore important that the surfaces remain as smooth and free of algae and crustaceans as possible. This is achieved by addition of antifouling additives.
The combination of all required properties leads to the formulations of marine paints being abrasive in processing. The above mentioned factors consequently influence the equipment of suitable agitator bead mills.
We can assist you in selecting the suitable wet-milling technology for marine paints and coatings, the right machine size and optimum process control.
