Our hydrated sodium disilicate contains both silica and alkalinity in a molar ratio of 2:1 between silica and sodium oxide. In addition, as it is hydrated it contains 18% of water which improves it's solubility. Our powder range has been specifically developed to meet the demand for different rates of solution and reactivity. Sodium disilicate is a sodium silicate with a SiO2/Na2O molar ratio of approximately 2,00 and a solid content of 82%.

Safety & Health
- Safety and Handling
Sodium trisilicates are alkaline products which are classified as irritating. They should be handled with care in order to prevent injuries. Whenever sodium trisilicate as a substance on its own or in a preparation is handled outside closed systems, suitable personal protective equipment (gloves, goggles, dust masks or respirators) is the preferred and only measure of control.
