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

摘要

A coating composition (I) for coil-coating processes comprises: (a) a binding agent comprising at least one aliphatic, araliphatic and/or aromatic polyester having an acid number of less than 10 mg KOH/g, a hydroxyl number of 30-200 mg KOH/g, and a number average mol. wt. of 1000-5000 Daltons and; (b) a cross-linking agent comprising at least two amine group-containing resins of different reactivity. An Independent claim is also included for a process for the production of the coating composition (I) by grinding the component (a) to a particle size of less than 20 mum, addition of component (b) followed by homogenization of the mixture.
