While Asterion provides a fully blended nickel brightener system, there are times when special support additives are needed. Asterion offers a full line of nickel wetters, leveling agents, grain refiners, ductilizing agents, low current density boosters and iron controllers. All are formulated for compatibility with the Asterion line of high performance nickel plating additives. These support additives are to be used occasionally so that the fully blended products may be added on an amp hour basis to maintain the concentration of additives needed to produce reliable and consistent results.
