Introduction to Potassium Silicate Powder

Commonly named dry potassium silicate powder, instant potassium silicate powder or potassium water glass powder, potassium silicate powder is a solid powdery inorganic silicate material processed by deep dehydration and ultrafine crushing of liquid potassium silicate. It completely retains the excellent chemical properties of liquid potassium silicate while overcoming the defects of liquid products such as inconvenient transportation, easy leakage and short storage period.

Under standard room temperature and atmospheric pressure, it appears as white or off-white free-flowing fine powder, with excellent bonding strength, rapid hardening performance, outstanding weather resistance, water resistance and corrosion resistance. Compared with sodium silicate powder, this water soluble potassium silicate powder has better alkali stability, stronger permeability and anti-efflorescence performance, especially suitable for high-standard construction reinforcement and high-temperature resistant material production. Our mainstream instant potassium silicate powder maintains a balanced silica-potassium oxide molar ratio, moderate reaction activity and stable physical and chemical indexes. It covers all mainstream application scenarios of powdered potassium silicate, winning long-term recognition and stable orders from global manufacturers with reliable batch consistency, high cost performance and diversified packaging options for bulk buyers.
