Features & Benefits
- Materials Features
- Product Features
- The silicone oil treatment guarantees the very marked hydrophobia of the product
- Very efficient effect in the thickening and thixotropy of complex polar liquids, such as those based on epoxy, polyurethane, or vinylester resins
- With silicone oil treatment, AEROSIL® R 208 offers a tailor-made chemical surface treatment.
- 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.
Applications & Uses
- Cable Gel Applications
Use of AEROSIL® fumed silica for cable gels gives excellent performance when it comes to shear-thinning, providing quick recovery and the gel does not require heat to be applied. AEROSIL® fumed silica improves properties of oil-based filling compounds for wire and cables to protect fibers (e. g. optical fibers) as it:
- Supports to isolate sensitive optical fi bers from external forces
- Protects the fi bers from moisture
- Provides thickening to help the gel to stay where it is placed
- Helps to form a seal to keep out contaminants like dust, dirt and water
- Is non-conductive / does not negatively infl uence di-electrical properties
- Applications
- Thickening and thixotropy control of adhesives and sealants for fiberoptic cables
- Thickening and thixotropy control of epoxy and vinylester resins
- 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
