Hoffmann Mineral Highlighting Aktisil, Aktifit

11.30.16

Hoffmann Mineral is highlighting at CHINACOAT its silane-treated products Aktisil (standard grade) and Aktifit (calcined grade).

Aktisil is made by treating the surface of Neuburg Siliceous Earth with chemical agents, mostly silanes. Aktifit is based on the standard product Sillitin Z 86. A thermal process is used to expel the crystalline water in the kaolinite portion and new mineral phases are formed practically amorphous. The silica portion remains inert at the temperature used. The resulting products have an outstandingly high degree of white and color neutrality.

According to Ursula Golling, marketing manager, the most interesting application fields for these products are wood and coil coating, partially replacement of TiO2, anti-corrosion  and powder coating.

“Advantages of this functional filler are good mechanical properties, as well as good chemical and abrasive resistance,” Golling added.
