Solución de silicato sódico (agua de cristal)
Sodium silicate solution (water glass)
Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 2000 · Certificado de Análisis (CoA) con cada lote
Sodium silicate solution, commonly called water glass, is a versatile inorganic compound used as a binder, adhesive, and corrosion inhibitor in industries like construction, ceramics, and detergents. Its alkaline properties make it ideal for pH regulation, water treatment, and even as a food additive (E550). This aqueous solution features a CAS number of 1344-09-8, molecular formula Na₂O₃Si (simplified as Na₂SiO₃), and an approximate molecular weight of 122.063 g/mol. It requires ambient storage but carries a **Danger** signal word due to its corrosive and hazardous nature. Molekula supplies sodium silicate solution from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
