REMOVABLE MASKANTS

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

FEATURES AND BENEFITS

• Excellent chemical resistance against etching media
