Safety & Health

Safety Classification
  • The classification of soluble silicates in accordance with European standards for dangerous substances depends on their molar ratio n and solids concentration.
  • According to Regulation EC Nº 1272/2008 can be established:
  • Lumps and solutions with n > 3.2 and %solids < 40%: are not classified as dangerous.

Lumps and solutions with 3.2 > n > 2.6
