METHOD OF COATING METAL PIPES WITH THE POWDER, AND USE OF THE COATING POWDER FOR THE SINGLE-COAT COATING OF THE OUTSIDE SURFACES OF METAL PIPES

摘要

The invention concerns coating powders containing epoxy resins, phenolic cross-linking agents, catalysts, fillers and, optionally, auxiliaries and additives. The coating powders are characterized in that crystalline silicilic acids modified to include glycidyl functional groups are used as fillers. The invention also concerns a method of coating the outside surfaces of metal pipes with the coating powders described and the use of the coating powders for the single-coat coating of the outside surfaces of metal pipes.
