COLOURLESS 25-50% SODIUM SILICATE SOLUTION IN WATER

Chemical dangers
The solution in water is a medium strong base. Reacts with aluminium and zinc forming flammable/explosive gas (hydrogen - see ICSC0001).

Occupational exposure limits
TLV not established.
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

Effects of short-term exposure
The aerosol is irritating to the eyes, the skin and the respiratory tract.


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Relative density (water = 1): 1.4
Solubility in water, g/100 ml at 20°C: miscible
