- Recommended Applications
SiSiB® FS-0250 can be applied as a thickening and thixotropic agent in many organic systems, e.g. in unsaturated polyesters, coatings, printing inks, adhesives, cosmetics and others. It is used as a reinforcing filler in elastomers, mainly silicone-elastomers, like HTV and RTV-2K. SiSiB® FS-0200 can act as a free flow additive in the production of technical powders, in food and feed and in pharmaceutical products.
