Powdered sodium silicate hydrated (hereinafter sodium hydrosilicate or powder) is designed to obtain sodium water glass by dissolving it in water under natural conditions at a positive ambient temperature.

The process of dissolution of sodium hydrosilicate occurs with the release of heat, dissolve with constant mixing to prevent the formation of powder lumps, which prolong the dissolution time.

The density of the required liquid glass depends on the concentration of the powder, which is indicated in the table:

Glass density, g / cm3 1.40 1.41 1.42 1.43 1.44 1.45 1.46 1.47 1.48 1.49 1.50
Powder concentration in solution, % not less 48.3 49.1 50.0 50.8 51.7 52.5 53.2 54.2 55.0 55.8 56.6


  • on their basis, it is possible to make compositions containing all the necessary components in the form of a dry mixture and ready for use after mixing with water, such compositions, subject to proper storage, can have an unlimited shelf life;
  • fast - dissolving hydrated silicates are more economical in transportation; unlike liquid glasses, hydrated silicates can be operated in wide temperature ranges (liquid glasses freeze even at low negative temperatures);
  • if necessary, from hydrated silicates, you can easily prepare water glass with the required modulus and concentration directly at the point of consumption.


Store in polyethylene bags in accordance with GOST 17811 or in soft disposable containers such as MKR - 1, OM, or in other packaging that ensures the safety of the product.

The guaranteed shelf life is 12 months from the date of manufacture.
