Anticaking


The anticaking effect: Evonik silica improve storage stability for powders and prevent clumping


SIPERNAT® specialty silica and AEROSIL® fumed silica from Evonik prevent powders from clumping during storage and shipping, and ensure that they flow well. Known as the “anticaking” effect, this phenomenon is closely related to the “free-flow effect”, except that the free-flow effect is a function of flowability at a given moment, whereas the anticaking effect is related to long-term stability.
