Schottel add new corrosion protection for rudder/propellers

0

Schottel have adopted an optimized coating process on their rudder/propellers. The new coating promises maximum corrosion protection due to optimized resistance to abrasion and greater adhesive force in combination with thicker coats of paint.

Underwater elements of the propulsion unit are being coated with several layers of extremely hard, two-component epoxy resin. Compared with a conventional standard coating, this is characterized by 2.3 times greater abrasion resistance and approx. 60% greater adhesion. For the above-water sections, SCHOTTEL uses a very dense and extremely durable two-component polyurethane coating.

Production is being carried out at a new plant near the company’s headquarters in Germany, opened in 2015. New blasting booths form the basis for substrate preparation of the entire Rudderpropeller in accordance with the strictest cleaning standards. The coatings now used by SCHOTTEL meet the requirements of the highest corrosion protection class C5-M (Very high (marine)).

The environment also benefits from the new processes – both during production and with regard to the vessel itself: the paints contain considerably lower quantities of volatile organic compounds and solvents. The coatings are also harmless to aquatic organisms.

The very smooth surface also inhibits the adhesion of marine organisms, thereby also contributing to improved durability and efficiency.
If requested by the customer, an optional, self-polishing, antifouling final coat can also be applied.

The new coating systems can also be combined with paints of older generations as well as with most two-component epoxy and polyurethane coatings.
