Liquid sodium glass
Sodium liquid glass is an aqueous solution of sodium silicate. The chemical formula is the sum of two oxides: Na2O+SiO2. Liquid glass is a binder and is widely used as a universal glue to connect glass, paper, metal and wood. It is made of silicate stationery glue. In the construction of liquid glass are used as additives and impregnation. Mixtures based on liquid glass used for production of putties and plasters, giving the processed elements of the anti-corrosion properties and protects them from exposure to high temperatures, as well as for waterproofing of slabs, basements and wells. Additive in cement mortars improves their strength and insulating properties. Non-combustible silicate paints based on liquid glass is used for painting areas with mass visiting of people, the manufacture of theater curtains, etc.
Warranty period of storage: 1 year from date of manufacture.
Hazard class: 4 (low hazard substances).
Within GOST 13078-81 share of liquid glass on three main types:
- Flowable with silicate module 2,3-2,8;
- Normal with silicate module 2,8-3,2;
- High modulus, silica modulus 3,2-3,6.
The most common sodium liquid glass with silicate module 2,8-3,0 and a density of 1,44-1,48 g/cm3.
