Description

Sodium metasilicate pentahydrate is able to integrate many hydrones to achieve better moisture absorption effect. Sodium metasilicate anhydrous is an inorganic, non-toxic, tasteless and environment-safe white powder or crystalline granules. It is 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 buffering PH value.
