Propulsion and steering manufacturer Schottel announced that it now offers more robust Rudder propellers thanks to optimized coating processes. The company claims that the result is maximum corrosion protection due to optimized resistance to abrasion and greater adhesive force in combination with thicker coats of paint.
The components of the propulsion units that are underwater are coated with layers of two-component epoxy resin that gives over twice the abrasion resistance and 60% greater adhesion than conventional coatings. For the above water sections, Schottel has used a dense and durable two component polyurethane coating.
According to Schottel, the coatings are less environmentally damaging both during production and with the vessel itself. The paint does not contain many volatile organic compounds and solvents and the coatings are harmless to aquatic life. Furthermore, the coatings inhibit the adhesion of marine organisms to enhance durability and efficiency.
The company adds that the coatings meet the requirements of the highest corrosion protection class C5-M and if required, they can be self-polished and an antifouling final coat applied. The new coatings can also be combined with paints of older generations.
