Enthone Inc.’s PFOS-free wetting agents/fume suppressants (WAFS) for decorative and hard chrome applications are designed to be environmentally sound, high-performance solutions that address pending U.S. EPA rules on the use of perfluorinated octane sulfonate (PFOS) fume suppressants for plating processes.

Enthone Inc.’s PFOS-free wetting agents/fume suppressants (WAFS) for decorative and hard chrome applications are designed to be environmentally sound, high-performance solutions that address pending U.S. EPA rules on the use of perfluorinated octane sulfonate (PFOS) fume suppressants for plating processes.

The EPA is expected to approve a law later this year that will restrict the use of PFOS-based WAFS used in chromic acid anodizing, decorative chromium electroplating and hard chromium electroplating. The company says its PFOS-free solutions also minimize air emissions, while reducing worker exposure to hexavalent chromium.

The company’s Ankor Wetting Agent FF is formulated to prevent misting from decorative hexavalent chrome solutions based on formation of a foam blanket. Ankor PF1 is designed to reduce the surface tension of hexavalent chrome solutions with low foam generation. It is stable at elevated temperatures and can be used to reduce misting in operations such as hard chrome, decorative chrome and anodizing. The company’s Udique Wetting Agent PF2 is low foaming and also reduces surface tensions designed for use in chromic acid etch solutions found in plating on plastics applications.
