High Performance Additive for Powder Coatings

Powder coatings are applied electrostatically and are then heat cured to allow them to flow and form a coating. Finally, they have a hard surface finish that is much tougher than a conventional paint, which results in excellent chemical and environmental resistance (1,2). 

Fumed metal oxide products may help to improve the color performance, processing, application and mechanical properties of powder coatings (1,2). 

In particular, fumed alumina and fumed silica products provide tribo-charging, free-flow, fluidization and anti-blocking in powder coating applications. Typically, fumed alumina is used for tribo coating processes and either fumed silica or hexamethyldisilazane treated fumed alumina is selected for corona coating processes (3).
