Abstract
A polysulfide coating composition includes an aliphatic, aromatic or cycloaliphatic material with at least 2 thiol groups; an aliphatic, aromatic or cycloaliphatic, acryl, polyester or polysiloxane-based material with at least two epoxy groups; and a catalyst. The coating provides a durable cavitation- and erosion-resistant coating for the rudders of ships, and is also suitable for sound-damping applications.
