Sodium Metasilicate Anhydrous
Sodium Metasilicate Anhydrous is generally immediately available in most volumes. High-purity Sodium Metasilicate Anhydrous is a multifunctional product that shows excellent pH-regulating capacity, efficient detergency, effective corrosion inhibition, good dispersing and bleach-stabilizing properties, and is environmentally safe. The advantage of our anhydrous metasilicate is the high active content and its purity, which makes it possible to formulate highly concentrated products.
Properties & Advantages
- White and free-flowing granules / powder.
- Dissolves easily, even in cold water. High bulk density and low dust content.
- Negligible insoluble residues.
- As a highly alkaline product, Sodium Metasilicate readily reacts with CO2. Our production methods are such that the risk of partial inactivity due to CO2 contamination is minimal, as there is no contact between our products and combustion gases. In this way, we can guarantee a pure Sodium Metasilicate.
