Specification

The Sodium metasilicate, with the CAS registry number 99734-09-5, is also known as Sodium metasilicate,anhydrous.It belongs to the inorganic chemical industries. This chemical's molecular formula is Na₂SiO₃ and molecular weight is 122.06. What's more,Its systematic name is Disodium metasilicate.Sodium metasilicate is used along with magnesium silicate, in muffler repair and fitting paste.It can be used to seal leaks at the head gasket and has been widely used as a general purpose cement, but especially for applications involving cementing objects exposed to heat or fire. It has also been used as a general purpose paper cement. Sodium silicate was also used as an egg preservation agent in the early 20th Century with large success. It was used as a timber treatment for pressure-treated wood in the 19th century and as a water treatment in waste water treatment plants.Physical properties about Sodium metasilicate are:(1)#H bond acceptors: 3; (2)#H bond donors: 2; (3)#Freely Rotating Bonds: 0.

Sodium metasilicate may cause damage to health.When you are using it, please be cautious about it as the following: (1)Causes burns; (2)Irritating to the respiratory system; (3)Irritating to eyes, respiratory system and skin; (4)Keep away from food, drink and animal feeding stuffs; (5)In case of contact with eyes, rinse immediately with plenty of water and seek medical advice; (6)In case of accident or if you feel unwell, seek medical advice immediately (show label where possible); (7)Avoid contact with skin and eyes; (8)Wear suitable protective clothing, gloves and eye/face protection.The Safety Information of Sodium metasilicate: (1)RIDADR:UN 3253 8/PG 3; (2)WGK Germany:1; (3)RTECS:VV9275000; (4)F:3; (5)TSCA:Yes; (6)HazardClass:8; (7)PackingGroup:III; (8)Transport Information:UN 325.
