PROCESS FOR THE PREPARATION OF CATIONIC BINDERS FOR COATINGS AND THEIR USE

摘要

2502/US-3480 Binders for cathodic electrodeposition coatings based on epoxy resin-amine adducts are obtained by incorporation of oxazolidone structures in combination with diamine bridges built up in a specific manner. The modified epoxy resin-amine adducts are used in electro-dipping coatings together with crosslinking components. The stoved coating films have excellent corrosion protection, especially at the edges of workpieces.
