Sodium Metasilicate

(Na2SiO3)

Sodium Metasilicate Anhydrous (Na2O.SiO2)

This product possesses high alkaline and defoul character, which is easy to soluble in water, good dispersibility and emulsifiability, not soluble in alcohol. It will deliguesce after absorbing moisture and carbon dioxide from the air.

This product is mainly used in making high efficiency detergent and metal cleaner. Instead of STTP, it can raise cleaning efficiency and reduce environmental pollution, provides excellent alkaline buffer, corrosion prevention for metal (i.e Zinc, Aluminium), possesses the character of softening water.
