Hydrophobic fumed silica
- Homogeneously hydrophobic surface
- Effective in the rheological control of complex liquid systems (such as paint and coating systems, adhesive and sealant materials)
- Efficient effect as flow agent
- Fine particle size
- stabilization of pigments
- enhanced effect of corrosion protection
- Improves incorporation and handling due to a homogeneous and gentle densification
- reduces dust development
Anti-settling agent and for pigment stabilization in coating applications
The hydrophobia guarantees the efficient effect as flow agent in very different applications, such as powder coatings, toners, or cosmetics
Rheology control for brilliant clear coat and top coats, such as acrylic/isocyanate coating formulations
Enhances the anti-corrosion properties for coatings
adhesives and sealants
We recommend to store the product in closed containers under dry conditions and to protect the material from volatile substances. AEROSIL® R 805 VV 90 should be used within 2 years after production.
