COATING MATERIALS AND THE USE THEREOF FOR THE PRODUCTION OF WELDABLE COATINGS

摘要

Disclosed are coating materials for coil coating methods, containing (A) at least one aliphatic and/or aromatic polyester having an acid number of < 10 mg KOH/g, a hydroxyl number of 30 to 200 mg KOH/g, and an average molecular weight (Mn) between 1000 and 5000 Dalton as a bonding agent, and (B) at leas t two resins which contain amino groups and have a different reactivity as crosslinking agents. Also disclosed are methods for the production thereof a nd the use thereof as coil coating enamels.
