Internal & External FBE Powder  coating Structure:
The epoxy powder is a kind of thermosetting nontoxic coating, forming the high molecular weight cross-linking structure coating after solidifying, featuring good chemical anticorrosion and higher mechanical properties. The function of epoxy powder bottom layer is to form continuous coating, providing excellent adhension by agglutinate and solidifying the steel tube surface with good  chemical resistance and cathodic disbanding resistance. The function of polymer adhesive is to agglutinate the epoxy powder before gelation, and to agglutinate the polyethylene top layer, which unites all three layers together.
