Details
Liquid Sodium Silicate, also known as Water Glass, is a multi-purpose alkaline sodium silicate solution with a variety of industrial, construction, ceramic, adhesive, and water treatment applications. This NSF grade sodium silicate solution is certified to NSF/ANSI 60 as a drinking water additive, with a maximum use dose of 265 mg/L. It has a SiO2/Na2O ratio of 3.20, a density of 41.1° Baume, and total solids of approximately 37.60%.
It is commonly used as a foundry-grade binder, ceramic deflocculant, carton adhesive-grade product, concrete and plaster sealer, and high-temperature bonding agent. It can also be used for surface applications, solid sand molds for metal castings, and wood treatment applications. Note that liquid sodium silicate is strongly alkaline, with a pH of approximately 11.3, and should be handled with proper care.
Certified to NSF/ANSI 60 for drinking water treatment applications, with a maximum use dose of 265 mg/L.
Used as a foundry-grade binder for instant solid sand molds in metal castings.
Can be diluted to lower concentrations as required.
Used in ceramic applications as a deflocculant to help prevent greenware shrinkage.
Suitable for carton adhesive applications and other bonding uses.
Can be applied to surfaces to create an instant antique look.
Used as a sealer for plaster and concrete surfaces.
Can be used as a wood treatment to improve water resistance and help deter insects.
Functions as a high-temperature adhesive and bonding agent when applied in a thin layer between surfaces.
Used in adhesives and binders, agriculture, cements and construction materials, detergents, drilling, geotechnical and mineral processing, manufacture of other chemicals, pulp and paper, textiles, and water treatment.
Liquid sodium silicate is strongly alkaline, with a pH of approximately 11.3. Use care when handling this product and wear gloves and eye protection to help prevent skin and eye irritation or burns. Avoid contact with eyes, skin, and clothing. Use only as directed and determine suitability for the intended application before use.
