Innovative manufacturing process simplifies dispersion of AEROSIL® silicas | Evonik

Evonik's Coating Additives business line has used an innovative process technology to develop four new fumed silicas from the AEROSIL® family that are much easier to disperse: The new product group consisting of AEROSIL® E 805, AEROSIL® E 812, AEROSIL® E 972 and AEROSIL® E 9200 is such that formulators can omit the time-consuming and costly grinding step, for example with a bead mill, when incorporating them into paints or coatings. The four new easy-to-disperse (E2D) products - like their alternatives in the standard range - are suitable for rheology control in both pigmented and clear coating formulations. The dispersion process for rheological additives - such as fumed silica - used to be complex and time-consuming. Now, if the formulator uses the new AEROSIL® E products, the use of an energy-intensive bead mill is no longer necessary.
