Abstract

Un procedimento per la rimozione di rivestimenti a base di resine fluorocarboniche da un substrato metallico, in cui il rivestimento è trattato con raggio laser per progressivamente colpire l'intera superficie del rivestimento stesso fino ad ottenere la delaminazione di esso dal substrato.
