Zusammenfassung:	Disclosed is a composition for improving the corrosion resistance of metals coated with 2K coatings. The composition comprises the reaction product of an aromatic sulfonyl isocyanate and an alcohol or polyol monomer. Also disclosed is a method of improving the corrosion resistance of metals coated with 2K coatings by the addition of a sulfonyl urethane-alcohol composition reaction product of an aromatic sulfonyl isocyanate and a mono¬ alcohol or poly-alcohol. L'invention concerne une composition pour améliorer la résistance à la corrosion de métaux revêtus de revêtements 2K. La composition comprend le produit de réaction d'un isocyanate de sulfonyle aromatique et d'un alcool ou d'un monomère de polyol. L'invention concerne également un procédé d'amélioration de la résistance à la corrosion de métaux revêtus de revêtements 2K par ajout d'un produit de réaction de composition de sulfonyle uréthane-alcool d'un isocyanate de sulfonyle aromatique et d'un mono-alcool ou poly-alcool.
