Sodium silicate, also known as liquid glass, is an aqueous solution of SiO2 (silicon dioxide) and Na2O (sodium oxide), whose variation in weight ratio between the two oxides and content of solids in the solution gives us many types of sodium silicates, each with specific characteristics for different uses in various market segments.

Sodium silicate is easy to manipulate, non-toxic and non-flammable. It has a broad spectrum of application, in addition of being a substitute in formulations and processes seeking an eco-friendly alternative.
