Sodium Metasilicate Pentahydrate
Detailed Product Description
Sodium Metasilicate Pentahydrate.
Sodium metasilicate pentahydrate is an inorganic white powder or crystalline granules, non-toxic, tasteless and environment-safe. It is easy soluble in water, insoluble in alcohol or in acid producing an alkaline solution, very hygroscopic when reacting with CO2 and water from the air. It has the capabilities of removing scale, emulsifying, dispersing, wetting, penetrating, and also has the capability of buffering PH value.
