Abstract

A novel cationic benzotriazole pigment (CBP) based on the benzotriazolium cation (BTAH2+) exchanged into a sulfonated organic resin has been synthesized and evaluated as a means of inhibiting the corrosion-driven cathodic disbondment of organic coatings from the surface of galvanized steel. The CBP...
