With its nanoparticle size and hydrophilic reactive sites on the particle surface, colloidal silica finds a many uses in industrial markets such as:
- Coatings - Preservation of color/transparency with these properties
- Reinforcement of coating strength
- Improved scratch and mar resistance
- Matting
- Antiskid
- Catalysts - ultra-pure colloidal silicas as
- binders
- pure silica source
- support for catalytic functionalities
- Chromatography - spherical silica particles with unimodal size distributions and low metals content.
- Investment Casting - High temperature binder
- Textiles -
- Anti-Corrosion Coatings
- Vacuum-Formed Fibrous Refractories- binders
- Ceramics- binders
