Potassium Silicate Used in the Construction Industry
● Potassium silicate, the core component of concrete seal hardeners, penetrates and reacts to form C-S-H gel, improving hardness, abrasion resistance, and dust prevention.
● As a binder in inorganic architectural coatings, it offers flame retardancy, breathability, and aging resistance.
● As a penetrating waterproofing agent, it is suitable for bridges, exterior walls, and other high-weatherability applications.
Potassium Silicate Used in the Agriculture Industry
As a water-soluble silicon-potassium fertilizer, potassium silicate enhances the mechanical strength of crop stems (lodging resistance), induces epidermal silicification to improve pest and disease resistance, and improves fruit quality.
Potassium Silicate Used in the Glass Industry
Potassium silicate is mainly used to make fire-rated glass interlayer liquids. The glass produced is widely installed in fire-rated doors, windows, partitions, curtain walls, and fire exits, and is often seen in malls, hospitals, high-rise buildings, and ships.
Potassium Silicate Used in the Coating Industry
Potassium silicate enables inorganic intumescent coatings to form a dense fire- and moisture-resistant barrier on steel, concrete, timber, and cables, protecting structural integrity.
Potassium Silicate Used in the Welding Material Industry
In the welding materials industry, potassium silicate serves as a binder that firmly adheres the electrode coating (comprising various mineral powders) to the welding core, while also functioning to stabilize the arc and facilitate slag formation.
Potassium Silicate Used in the Refractory Materials Industry
In the refractory sector, potassium silicate serves as a high-temperature binder that bonds refractory aggregates-including high-alumina and siliceous materials-into refractory products or monolithic refractories for high-temperature furnace linings.
Potassium Silicate Used in the Electric Industry
Electronic-grade potassium silicate is used as a binder for phosphor in cathode ray tubes and as a cleaning agent for semiconductor wafers.
Potassium Silicate Used in the Textile Industry
In the textile industry, potassium silicate can be used as a fiber treatment agent to enhance the softness, wrinkle resistance, and abrasion resistance of fibers.
