ESSEN, Germany — Evonik has received the 2020 Ringier Coating Technology Innovation Award for its AEROSIL^® Fumed Silica Dispersion VP. Disp. WF7620, a new rheology control dispersion designed specifically for waterborne systems.

How to improve the rheology performance of water-based coatings is one of the big challenges faced for the waterborne formulation. VP Disp. WF 7620 is the newest rheology control dispersion in the Evonik Coatings Additives portfolio. The dispersion was specifically developed to control the rheological properties of waterborne coatings.

Compared to other traditional thickeners and rheology control agents, VP. Disp.
