Polyurethane Mirror Chrome Powder Coat , RAL 1007 Color Rough Powder Coating
RAL1007 daffodil yellow food grade mirror chrome Polyurethane powder coating
Both chemistries provide fairly good chemical resistance however polyurethanes significantly outshine polyesters if formulated appropriately. In fact a highly crosslinked polyurethane powder coating provides chemical resistance that rivals epoxy powder performance.
