SK-200S Hydrophobic Fumed Silica
Features:
SK-200S is a hydrophobic fumed silica treated with hexamethyldisilazane, derived from hydrophilic fumed silica with a specific surface area of 200 m²/g. It is better suited for powder materials, oil-based systems, and medium to high polarity systems.
Properties:
- Exhibits low thickening effect and good dispersibility in defoamers, significantly enhancing defoaming speed and extending foam suppression time.
- The product undergoes deep processing, ensuring stable structure and maintaining low hygroscopicity in powder form even after long-term storage.
- Used as a triboelectric powder and flow aid in powder coatings, it can improve the powdering rate.
- Serves as a dispersant in dry-mixed colorants and other pigments.
- Acts as a reinforcing aid in plastic products and polymer materials.
Applications:
- Defoamers
- Powder materials with low hygroscopicity requirements
- Powder coatings (internal additive) and other powder materials
- Dry-mixed colorants
- Plastic products and polymer materials
