A METHOD FOR APPLYING ANTI-CORROSION COATINGS THAT ARE DEVOID OF CHROME COMPRISING DITHIOPHOSPHINIC ACID AND/OR ITS SALTS

摘要

Use of dithiophosphinic acids of the general formula HS₂P(R¹)(R²) and/or salts thereof for producing chrome-free, polymer-containing corrosion control layers on metallic surfaces, R¹ and R² independently of one another each being organic radicals having 1 to 30 C atoms.
