Further dispersions of hydrophilic and hydrophobic silica and metal oxides in organic solvents are available on request.

The data represents typical values, not production parameters.

1) Solid contents may vary ±1%

2) Measured according to EN ISO 787-9 method

3) Measured according to DIN EN ISO 3219 at a shear rate of 100 s-1

4) Stabilized with small amounts of aluminum compounds.

Developmental products are labeled with the VP Disp. designation. Their commercialization depends on market response. Even though they are produced in commercial quantities, future availability should be verified. In some cases, these products may not have undergone complete testing.

 

Evonik has extensive knowledge, sophisticated equipment and many years of experience, all of which are necessary to produce high quality dispersions.

AERODISP® is the ideal solution for the dust-free handling of AEROSIL® fumed silica and AEROXIDE® fumed metal oxides. A special manufacturing process and many years of know-how enable us to provide these products in an exceptional state of dispersion. Further dispersions of silica and metal oxides in organic solvents are available on request.
