General Characterization

Aqueous anionic colloidal solution of amorphous Silicon dioxid.
Dispercoll® S 2020 XP is intended as a component for waterborne polychloroprene adhesives based on Dispercoll® C dispersions.
The proper viscosity for a particular application can be obtained through the addition of Nano-Zinc Oxide to the adhesive formulation. These adhesive formulations will show improved moisture resistance and a higher heat resistance.
Dispercoll® S 2020 XP is particularly suitable for 1-K spray formulations with low pH values on the basis of Dispercoll® C, which is due to its lower alkaline content resulting in an excellent storage stability.
