Evonik 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.
Waterborne coatings have gained significant recognition globally due to eco-friendliness.
However, 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.
This dispersion was specifically developed to control the rheological properties of waterborne coatings.
Compared to other traditional thickeners and rheology control agents, VP. Disp. WF 7620 can be easily used in the water-based formulation and shows excellent rheology performance in water-based coatings, providing an anti-settling effect in pigmented coating and anti-sagging effect in various applications. The product is ideally suitable for high-performance waterborne industrial coating applications, such as plastic, metal coatings and automotive coatings. It’s especially recommended to be used via spray applications.
VP Disp. WF 7620 is very easy to use and handle. It can trigger quick and complete dispersion under a water-based system, even under low shear conditions. This allows coating manufacturers to eliminate extra process steps such as pearl milling, which results in a faster, more efficient production process and higher rheological effectiveness of coating products.
"VP Disp. WF 7620 is a great choice for coating manufacturers who want to improve rheology performance for water-based coatings,’’ said Maximilian Morin, head of Market Segment Industrials Coatings, Evonik Coating Additives "Its universal rheology control properties enable water-based coatings with excellent stability in storage and anti-sagging properties in the application, creating a new application area of our leading AREOSIL product portfolio.”
“Evonik Coating Additives has a strong presence in China and Asia Pacific. The award-winning product VP Disp. WF 7620 represents Evonik’s continued commitment for the growing coating markets,” added Wei Yin, VP, head of Evonik Coating Additives Asia Pacific, “We will continue to strengthen our coating business and support our customers through investment in research and development and also production capacity and capability expansion.”
