colloidal silica&silica sol used for vacuum forming refractory fibrous shapes
Model No.: 12451515
Silica sol &Colloidal silica
Silica sol is a colloidal solution, odorless and non-toxic. Silica sol is a dispersion of nano-scale silica particles in water or solvent. Since the SiO2 in the silica sol contains a large amount of water and hydroxyl groups, the silica sol can also be expressed as SiO2.nH2O.
Inorganic Fibrous Shapes
colloidal silica is the binder used for vacuum forming refractory fibrous shapes such as:
Other parts requiring high temperature stability.
Resistance to thermal shock
Practically no thermal expansion
Resistance to mechanical shock and vibration
Flexibility in control of product properties
Usefulness at temperatures up to 1650°C (3000°F) with certain fibers
Properties of the composites can be varied by the type and amount of fiber or binder, different fabrication processes, post-treatments, and specialty coatings.
The maximum shelf life of different silica sol products is not the same, and they are all indicated in the product data sheet. Product storage time beyond the shelf life or storage under adverse conditions may affect the performance of the product.
Silica sol is a freezing-sensitive material. If allowed to freeze, the product will agglomerate into lumps or appear gelatinous and cannot be recovered. If the product is frozen, it is likely to become useless and must be disposed of. If exposed to higher storage temperature for a long time, the shelf life of the product will be shortened. In order to reduce the influence of temperature on silica sol products and maximize the shelf life, they should be stored at the recommended storage temperature of 20°C (68°F). Generally speaking, environmental conditions of 5°C to 35°C (+40°F to 95°F) are also acceptable, but please refer to the product data sheet for individual product storage recommendations.
