Dispercoll® S 4020

Aqueous anionic colloidal solution of amorphous Silicon dioxid. Dispercoll® S 4020 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.
