Colloidal silica
We produce colloidal dispersions of silica particles in water under the trade name Köstrosol®. The particles are made from high-purity alkali silicate. They are spherical and generally non-crosslinked and are hydroxylated at the surface.
The reactivity of our colloidal silica can be modified and changed according to their target application. The binder effect or the polishing properties of the materials can therefore be adjusted precisely.
For the optimum choice of material, select your product from our colloidal silica portfolio or tell us your specific application. We are happy to develop a product according to your specific application properties.
