AEROSIL® R812S is a fumed silica aftertreated with HMDS.

Applications

• Paints and coatings systems
• Silicone rubber
• Adhesives and sealants
• Cosmetics

Properties

• Effective rheology control in complex liquid systems (e.g. 2 pack-PUR coatings)
• can be applied in coatings systems as an anti-settling agent, for the stabilization of pigments and to enhance the effect of corrosion protection
• Free flow aid in powder coatings
• can easily be incorporated into silicone rubber formulations and improves their mechanical and optical properties

AEROSIL® R202 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
