Abstract
PURPOSE: To prepare a coating composition which has excellent adhesivity, flexibility and corrosion resistance and can be made cationic, by reacting a specific polyurethane prepolymer with a specific epoxy resin, and then reacting the product with a compound which can be made cationic.
CONSTITUTION: A polyurethane prepolymer having terminal isocyanate group and obtained by reacting a polyisocyanate (e.g. 2,4-tolylene diisocyanate) with a ≥2-functional polyhydroxy compound having a molecular weight of 300W3,000 and a hydroxyl equivalent of 200W1,500 (e.g. polyether polyol) is made to react with an epoxy resin having a hydroxyl equivalent of 150W1,500 and an epoxy equivalent of 150W1,500 (e.g. aromatic polyhydric phenol) at an NCO/OH ratio of 0.05W1.0. The objective resin can be obtained by reacting the product with a compound having a group which is reactive with epoxy group and can be made cationic (e.g. hydroxylamine having hydroxyl group).
