VWR Disodium Metasilicate Pentahydrate, TECHNICAL grade, is a highly alkaline, water-soluble silicate compound widely used in cleaning formulations, water treatment, degreasing, surface preparation, and corrosion inhibition. Its buffer capacity and ability to disperse oils, greases, and particulates make it an excellent base for industrial detergents and alkaline cleaning agents.
Key Features
- TECHNICAL Grade – Cost-effective solution for industrial and cleaning use
- Alkaline Compound – Effective for grease cutting and emulsification
- Pentahydrate Form – Stable, easily handled crystalline powder
- Multifunctional Agent – Acts as a builder, pH buffer, and anti-redeposition aid
- Water-Soluble – Rapidly dissolves in aqueous systems
