SiSiB® FS0201 is used for controlling rheology and thixotropy in liquid systems. It functions as an anti-settling, thickening, and anti-sagging agent, improving the free flow and anticaking properties of powders. With its high purity and low humidity content, it has no impact on taste or the natural color of powder formulations.
SiSiB® FS0201 is supplied in multiple layer 10 kg bags.
In the original unopened packaging, SiSiB® FS0201 has a shelf life of 24 months under dry conditions.
