KratonTM  G SEBS and KratonTM  D SBS polymers are well suited for producing protective, removable films used as chemical milling and blanking maskants.  The high-strength polymer films are dip- or spray-applied to metal work pieces during chemical processing.  When the milling operation is complete, film is readily removed leaving no residue on close-tolerance, finely detailed etched surfaces.  Kraton G SEBS and D SBS polymers are soluble in a wide range of common solvents; they offer excellent resistance to chemicals used in the milling process.
