Silicones are used in numerous applications and enhance the functionality of a growing number of products. To name a few, our products enhance the performance of waterborne coatings by providing cure resistance while increasing the durability and strength of cementitious operations. Choosing the right silicone can be a challenge. Subtle differences exist in particle morphology, particle size, and ion species.
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: electronics chemicals, paper chemicals, ceramics, sapphire polishing, gallium arsenide, silicon wafer polishing, cement curing agent, refractory materials, etc.
