New rheology dispersion for spray application combines the best of both worlds
- Higher compatibility than existing dispersions
- Highly efficient anti-settlement and anti-sagging
- Highest rheological performance in waterborne coating formulations of all fumed silica powders and dispersions on the market
Evonik Resource Efficiency introduces VP Disp. WF 7620 – the newest rheology control dispersion in the portfolio of its Coating Additives Business Line. The dispersion was developed specially for waterborne systems. Because viscosities are generally lower in waterborne systems, VP Disp. WF 7620 efficiently prevents anti-settlement in the liquid phase and anti-sagging during the application. Accordingly, it also increases pigment stabilization. Its main applications are high-performance waterborne coatings for the industrial and automotive industries. It is especially recommended to be used via spray applications.
The new dispersion has a very high compatibility. As a result, the usage of defoamers can be minimized or even eliminated altogether. Furthermore, VP Disp. WF 7620 has a wider range of uses as it doesn’t interfere with other ingredients of the formulation. It is suitable for pigmented and clear water-based formulations alike.
With the usage of VP Disp. WF 7620, customers can skip pearl milling and do not need any other high shear equipment to incorporate the additive into the formulation. The usage during the manufacturing process is in fact quite simple: The dispersion only needs to be stirred in, thus providing a high rheological effectiveness. Dispersions allow dust-free handling of AEROSIL® fumed silica powder in liquid media. They are ready to use and easy to handle.
VP Disp. WF 7620 belongs to Evonik’s product line of waterborne dispersions based on hydrophobic, or water-repellent, AEROSIL® fumed silica. The dispersion contains 20% of functional AEROSIL®.
