PHYSICAL STATE; APPEARANCE:
COLOURLESS 25-50% SODIUM SILICATE SOLUTION IN WATER

PHYSICAL DANGERS:

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 .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES
