Sodium Metasilicate 5H₂O & 9H₂O
Shreenath Marketing produces different grades of Sodium Metasilicate, mainly Pentahydrate (5H₂O) and Nonahydrate (9H₂O), which are widely used in various industries. It is made by fusing sodium carbonate and silicon dioxide at high temperatures. When dissolved in water, it forms a highly alkaline solution. Also known as water glass, it is a key ingredient in laundry and dishwasher detergents. It is used in the production of silica gel, paper, cardboard, textiles, paints, adhesives, ceramics, sanitaryware, foundries, and wood processing. It offers excellent binding, bleaching, cleaning, and sizing properties. It is safer than caustic soda and less aggressive on metals like aluminum. Sodium Metasilicate also forms a protective film on metal surfaces in the presence of water. It helps suspend fine particles in liquid, preventing them from settling. In cleaners, it enhances performance by neutralizing acids, emulsifying grease, and preventing dirt redeposition.
