Evonik AEROSIL fumed silica rheology control additives R805, R812, R812S, R816, R972, R974
Details

The rheological properties of paints and coatings can be adjusted according to requirements using hydrophilic or hydrophobic AEROSIL® products. In almost all solvent-borne, water-based, and high-solids coatings, the addition level is 0.3–1.0% based on the total formulation. Incorporation of AEROSIL® particles into coatings often results in pseudoplasticity associated with thixotropic effects.
