AEROSIL® R 202 Hydrophobic Fumed Silica

Evonik Industries, one of the world's leading specialty chemicals companies.

AEROSIL® R 202 is a fumed silica after treated with a polydimethylsiloxane. It is used for adhesives and sealants, epoxy-, vinylester resins, cable gels, and gelcoats. AEROSIL® R 202 helps with the thickening and thixotropy of complex polar liquids based on epoxy, polyurethane, or vinylester resins. It also helps the thickening and thixotropy of cable gels for fiber optic cables.

Specifications

AEROSIL® R 202 Hydrophobic Fumed Silica

AEROSIL® R 202 is a fumed silica surface-treated with polydimethylsiloxane.

Properties
  • 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 therefore 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.
  • At the same time, PDMS-treated, small particle AEROSIL® grades maintain good flowability.
  • The slightly oily effect of the PDMS treatment provides additional benefits in some printing processes.
Applications
  • Thickening and thixotropy control of adhesives and sealants for fiberoptic cables
  • Thickening and thixotropy control of epoxy and vinylester resins and gelcoats
  • Thickening and thixotropy control of cable gels, lubricants, and cosmetic formulations
  • Booster silica for defoamer formulations
  • Anti-sedimentation aid for fillers, such as chalk or quartz powder
  • Additive for formulation of anti-corrosion systems
  • Improves flowability of powders
  • Enables achieving of a high tribo-charge
