carried out in a pearl mill, for example, an AEROSIL® concen-tration of 5 – 8 % (related to solid binder) has proven success-ful. This makes it possible to work economically and to achieve an optimum degree of dispersion. The desired final concentra-tion of AEROSIL® is then obtained by means of reduction.

Streamlining customer production to boost efficiency

AEROSIL® fumed silica is manufactured by a continuous flame hydrolysis process of silicon tetrachloride SiCl4. During this process, SiCl4 is converted into the gas phase and then reacts spontaneously and quantitatively in an oxyhydrogen flame with the intermediately formed water to …

DISPERSION OF NANOSCALE SILICA PARTICLES USING A …

AEROSIL® is produced from compounds such as silicon chloride (SiCl 4) by means of flame hydrolysis. The chloride is first vaporized, then mixed with air and hydrogen and forwarded to a combustion chamber. The powdery white silica is created under the flame within a few seconds. The silica is left to cool, and then the solid matter is separated ...

Successful Use of Fumed Silica in Liquid Systems

The efficiency of the Aerosil can be increased by adding BYK-405. By using our wetting and dispersing additive BYK-W 969 (1 based on filler), you can increase the filler load (depending on your system, 10 to 15%) and the result is a very smooth putty formulation without any settling or sagging problems.
