SILICA-BASED RHEOLOGY CONTROL
SILICA-BASED RHEOLOGY CONTROL ADDITIVES
The rheological properties of paints and coatings can be regulated according to the needs with either hydrophilic or hydrophobic AEROSIL® grades. Added amounts of 0.3–1.0 %, based on the total formulation, are typical in nearly all solvent and waterborne systems, as well as in high solids coatings. The incorporation of AEROSIL® particles into a coating generally produces a pseudoplasticity that is often linked with a thixotropic effect.
