20191015&ensp·&enspFumed silica (CAS number 112945525), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, threedimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high


AEROSIL® for Paints and Coatings

2017102&ensp·&enspBy using AEROSIL® fumed silica, the gloss and coloristics of many pigmented coating systems are improved as a result of the increased degree of dispersion and the prevention of pigment reagglomeration during storage. Another significant effect arising from the use of AEROSIL® fumed silica is the improved water resistance and

Successful Use of Fumed Silica in Liquid Systems

Successful Use of Fumed Silica in Liquid Systems. October 1, 2001. At these rates, minimal energy is used to wet the fumed silica. Using this low shear rate, resulting thickening performance can be very inconsistent, batchtobatch. Other results of low shear rate are loss of efficiency, whereby more AEROSIL fumed silica needs to be added
