Colloidal silica
(Silica sol)

Silica sol or colloidal silica is a silica dioxide colloidal solution, which includes water and a so-called dispersed phase consisting of tiny (nanoscale) particles of amorphous silica.

Silica sol particles have a developed surface and the presence of silanol groups on it ensures the stability of the sol and the possibility of modification due to the sorption of molecules with other functional groups.

Buy silica sol from the manufacturer.

You can buy silica sol with a minimum budget, making the workflow of your enterprise more efficient and economical. Find out from our experts exactly how to use this material in the best way – they know all the ways and options for using silica sol in various industries and fields of work.
Silica sol in construction industry
These properties are appreciated by construction workers who add silica sol to concrete and cement mortar to improve its operating characteristics. The silica sol gives the following characteristics to the building material:

Endurance. In particular, the compression resistance, which significantly exceeds the performance of the raw material.

Resistance to corrosion. The protective film formed by silica sol prevents corrosion of metals.

Cold resistance. Protection from the chemical's aggressive effects.
Silica sol in industrial manufacture
Silica sol is often used in the foundry as a binder for casting-including because it has refractory properties. So, the product is used for the production of shell molds, as well as for the processing of molds for casting steel – the metal is easier to separate with silica sol.

Silica sol is often used in the foundry business as a component of a heat-resistant binder for casting on smelted models. On the one hand, because of the good refractory properties, on the other hand, because of the better binding properties compared to alumina.

Equipment that uses silicic sol (which you can buy without significant costs) serves longer, since it is less exposed to erosion.
Other ways of usage
Like quartz, silica sol has an insignificant high temperature expansion number, due to this the solution has become an obligatory part of the refractory ceramic materials production. In addition to fire safety, the composition is characterized by low toxicity.

It is noteworthy that the rails which are treated with a silica sol, achieve better indicators of the locomotive traction force – this is due to an increase of the machine wheels adhesion coefficient of adhesion with the metal surface of the rails.

Finally, silica sol receives numerous usage in light industry and in everyday life. It is added in cleaning agents, adhesive compositions, fabrics and paper, it is also used in water purification systems.
Silica sol in coatings
In the production of electric steel (silicon steel), silica sol is one of the main components of the protective coating – electrical insulation and anti-corrosion.
Silica sol in oil refining
Due to the developed specific surface area of silica particles, the product is widely used for the design of catalysts for various objectives. One of the most significant objectives is the efficient oil refining.
