Hydrophobic Fumed Silica

• The silicone oil treatment guarantees the marked hydrophobia of the product
• Highly efficient effect in the thickening and thixotropy of complex polar liquids, such as those based on epoxy, polyurethane, or vinylester resins
• Improves the water resistance of moisture-sensitive formulations, such as cosmetic preparations
• Improvement of the anti-settling behavior of pigments and anti-sagging behavior in 2-C epoxy coatings.
• With silicone oil treatment, AEROSIL® R 202 offers a tailor-made chemical surface treatment.
• Due to its excellent electrical insulating ability and low water absorption, this hydrophobized, small-particle silica easily acquires and conserves electrical charge
• It is typically used as a surface additive for toner particles in order to increase charge and improve flowability.
• The high hydrophobicity of PDMS-treated, small particle AEROSIL® grades makes them particularly effective for achieving a high tribo-charge.
• The slightly oily effect of the PDMS treatment provides additional benefits in some printing processes.
