摘要
Powder coating, process for the exterior coating of metal pipes, and use of the powder coating for the single-layer exterior coating of metal pipes. The present invention relates to powder coatings comprising epoxy resins, phenolic crosslinking agents, catalysts, fillers and, if desired, auxiliaries and additives. The powder coatings are characterized in that the fillers used are crystalline silicic acid modifications functionalized with glycidyl groups. The invention also relates to a process for the exterior coating of metal pipes using the powder coatings described, and to the use of the powder coatings for the single-layer exterior coating of metal pipes.
