Description
Generally, potassium silicates and sodium silicates share similar performance properties. However, in certain applications, there are a number of performance advantage of potassium silicate over sodium silicates.
Sodium silicates tend to react with atmospheric carbon dioxide to form carbonates and become progressively less water-soluble. Potassium silicate films are less likely than sodium silicate to develope a carbonate bloom or white efflorescent coat of alkali carbonate. Potassium silicate solutions are not as sticky or tacky as sodium silicate solutions, therefore easier to handle and use. The molar ratio is calculated as follows:
