Product Description
- Product Info：
- It is a hydrophilic fumed silica with a specific surface area of approximately 200 m²/g. Manufactured via high-temperature flame hydrolysis, QS-20 builds a three-dimensional network structure within formulations to deliver superior rheological control.
- Properties:
- Thixotropy: Controls rheology, anti-sag & anti-settling in coatings/adhesives.
- Reinforcement: Boosts HCR/RTV silicone rubber strength.
- Anti-caking: Improves powder free-flow.
- High Purity: SiO₂ >99.9%, Fe/Al <20ppm.
- Applications:
- Coatings & Inks: Water-based, UV, and leather finishes (anti-sag, clarity).
- Adhesives & Sealants: Viscosity control and anti-settling.
- Silicone Rubber: Reinforcing filler (HCR/RTV).
- Cosmetics & Food: Free-flow aid for powders and texture enhancer.
- Plastics: Anti-blocking and dispersion aid.
