Liquid Potassium Silicate

1. Product summary
  • The potassium silicate is manufactured by melting SiO₂ and K₂CO3 in a high temperature furnace, and the liquid potassium silicate is its water solution which appears transparent and colorless. The general chemical formula is K₂O nSiO₂ mH₂O. This is very commonly used as water soluble silicate inorganic solution along with liquid sodium silicate.

5. Caution
  • 1) Liquid Potassium Silicate is not a toxic material but it's harmless chemical used in tap water.

    · Furthermore, Cd, lead, hexavalent chrome, arsenic, and mercury are not detected in leaching test according to the notice from Ministry of Environment. However, it's not a food additive so it's harmful to human body when it's swallowed.


  • 2) Caution for handling Liquid Potassium Silicate

    · Clean skin thoroughly with water when it's exposed to Liquid Potassium Silicate solution.

    · When an eye is exposed to Liquid Potassium Silicate solution, wash your face with clean water and apply aboric acid solution to the eye and use eye-drops. - Keep it away from wound.

    · Wash clothes contaminated by Liquid Potassium Silicate solution as soon as possible before it becomes dry. because it may cause decoloration and it's hard to remove it once it's dry.
