Liquid Potassium Silicate 2.5-2.6 Modulus Application

Modulus 3.3–3.4 liquid potassium silicate solution (aqueous potassium silicate / soluble potassium silicate solution) is our flagship liquid silicate product. Relying on its prominent bonding, film-forming, fire-resistant, gelling and catalytic characteristics, it is widely used across multiple industries with detailed application scenarios as follows:
 

• Inorganic Coatings & Fireproof Materials Industry

 
As the primary binder raw material for water-based inorganic coatings, high-temperature fireproof coatings, fire-resistant mortar and exterior wall flame retardant layers. This potassium silicate aqueous solution forms dense, heat-resistant inorganic films after curing, greatly improving the fire resistance, weather resistance and hardness of coating layers for steel structures, tunnel linings and building fireproof panels. It is also used to produce inorganic thermal insulation coatings, anti-rust primer and high-temperature resistant surface treatment agents.
 

• Construction & Concrete Hardening Industry

 
Key additive for concrete densifiers, penetrating curing agents, tunnel shotcrete admixtures and waterproof sealing slurries. When mixed with concrete base materials, soluble potassium silicate solution reacts with cement hydration substances to form hard silicate crystals, lifting surface density, abrasion resistance and anti-permeability of factory floors, parking lots and underground engineering. It also serves as a stabilizer for road dust suppression and mine slope solidification.
 

• Welding & Foundry Industry

 
High-performance liquid binder for welding electrode coatings, precision investment casting shells and refractory castables. The aqueous potassium silicate features good fluidity and uniform coating performance, effectively enhancing the strength and high-temperature stability of casting molds, reducing sand sticking and casting defect rates. In refractory production, it bonds alumina, silica and magnesia raw materials to make high-temperature kiln linings, heat preservation refractory blocks for metallurgy and glass furnaces.

Frequently Asked Questions

What is the CAS number of soluble potassium silicate solution?

The CAS No. is 1312-76-1, consistent with standard industrial potassium silicate raw materials.

What modulus specifications do you supply for aqueous potassium silicate?

Standard modulus 2.4–3.9 is in stock. We can customize special modulus, concentration and viscosity according to customers’ production formulas.

What are the main differences between liquid potassium silicate and sodium silicate solution?

Potassium silicate aqueous solution has no efflorescence after curing, better high-temperature resistance, stronger weatherability and compatibility with agricultural formulations. Sodium silicate tends to form white salt bloom, so potassium version is preferred for high-end coatings, fireproof materials and silicon-potassium fertilizers.

Is this soluble potassium silicate solution ready to use directly?

Yes. It is a fully dissolved liquid product without solid particles. No heating or stirring dissolution is needed; you can mix it directly with water, fillers, surfactants or fertilizer liquids for production.

What packaging options do you offer for bulk orders?

We provide IBC totes, plastic drums and customized tank truck delivery. Flexible packaging supports small trial orders and large-tonnage bulk purchases, with stable quality across all batches.
