Potassium silicate Introduction

Potassium silicate is a colorless or slightly yellowish, translucent to transparent liquid with hygroscopic properties. It has a pH value between 11 and 12 and a relative density ranging from 1.16 to 1.45 (at 20°C). It exhibits strong alkalinity and decomposes in acids, precipitating silica. It dissolves slowly in cold water—or is practically insoluble, depending on its composition—and is insoluble in ethanol.

The higher the modulus of potassium silicate, the greater its viscosity and strength, and the faster the drying rate. Conversely, the lower the modulus, the better its film-forming properties, but the slower the drying rate.

Potassium silicate Applications:

Used in waterborne zinc-rich coatings and other eco-friendly water-based coatings.

Applied in high-temperature, thermal shock-resistant, and fire-retardant coatings.

Used in agricultural silicate fertilizers to provide plants with essential potassium and silicon.

Serves as a binder in welding electrodes and sand casting.

Applied in concrete strengtheners and floor hardeners.

Used in fire-resistant glass and protective liquids/coatings (depending on product form).
