Neutral Colloidal Silica/Silica Sol

Colloidal silica/Silica sol is a kind of colloid which is formed by nm-grade particles SiO2, dispersed in water. It is odorless, tasteless and nontoxic and its chemical molecular formula is mSiO2·nH2O.
1. The colloid particles are minute, and the particle size can be controlled according to customers' requirements.
2. Colloidal silica/Silica sol has relatively large specific surface area, and high heat-resisting performance (1500-1600"C).
3. With low viscosity, it can soak the places where water soaks; therefore, it presents excellent dispersion and permeability.
4. When the moisture contained in silica sol is evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.
Product application: coating, refractory industries, investment casting, polishing etc.

More Information About Neutral Silica Sol

Neutral colloidal silica, also known as silica sol, is a stable dispersion of silica particles in water. The particles are typically around 10 to 50 nanometers in size and have a highly uniform shape and size distribution.
Silica sol is neutral in pH and has a relatively low concentration of dissolved ions. It is widely used in various industries, such as coatings, paper and pulp, electronics, and textiles, due to its unique properties, such as high surface area, stability, and transparency.
In coatings, silica sol can be used as a binder to improve adhesion and durability of the coating, as well as a matting agent to reduce gloss. In paper and pulp production, it can be used as a strengthening agent to increase the strength and durability of the paper. In electronics, it can be used as a polishing agent to produce smooth and uniform surfaces. In textiles, it can be used as a finishing agent to improve water repellency and stain resistance.

Some of the common uses of silica sol are as follows:

Coatings: Silica sol is used as a binder in coatings to improve the adhesion and durability of the coating. It also acts as a matting agent to reduce the gloss of the coating and create a more matte finish.
Paper and pulp: Silica sol is used as a strengthening agent in the production of paper and pulp. It helps to increase the strength and durability of the paper, making it more resistant to tearing and breaking.
Electronics: Silica sol is used as a polishing agent in electronics to produce smooth and uniform surfaces. It helps to remove surface defects and imperfections, creating a clean and polished surface.
Textiles: Silica sol is used as a finishing agent in textiles to improve water repellency and stain resistance. It creates a barrier on the surface of the textile that repels water and prevents stains from setting in.
Adhesives: Silica sol is used in the production of adhesives to improve the bonding strength and durability of the adhesive. It also helps to reduce the viscosity of the adhesive, making it easier to apply.
Catalysts: Silica sol is used as a support material for catalysts in various chemical reactions. It provides a high surface area and stability, making it an effective support material for catalysts.
Overall, neutral colloidal silica/silica sol is a versatile material with a wide range of applications due to its unique properties. Its stability, transparency, and high surface area make it a valuable material in many industries.
