Concrete Curing and Hardening

Lithium silicate is a premium functional material widely used in concrete surface treatment and internal curing. With a stable modulus of 4.8–4.9, its low-alkali and low-shrinkage characteristics enable it to penetrate deeply into the capillary pores of concrete.

It reacts with free calcium hydroxide in concrete to generate insoluble calcium silicate hydrate crystals, which fill internal pores, densify the concrete structure, and significantly improve surface hardness and abrasion resistance.

Different from traditional sodium and potassium silicate, lithium silicate will not cause surface efflorescence, cracking or dimensional deformation after curing.

It can effectively lock concrete moisture, promote complete hydration of cement, and greatly enhance the durability, frost resistance and impermeability of concrete floors, bridge decks and building structural layers. It is the preferred curing agent for high-standard industrial floors and commercial building concrete protection.

High-grade Inorganic Coating Production

As an eco-friendly inorganic film-forming agent, liquid lithium silicate serves as the core base material for manufacturing high-grade inorganic fireproof coatings, weather-resistant coatings and architectural protective coatings.

Its excellent film-forming property and ultra-high weather resistance allow the cured coating layer to form a dense, hard and breathable inorganic protective film. The coating features strong adhesion to cement substrates, metal surfaces and wall bases, with outstanding anti-aging, UV-resistant and stain-resistant performance.

In addition, lithium silicate-based coatings are free of volatile organic compounds (VOCs), non-toxic and harmless, and possess excellent high-temperature resistance, which can maintain stable protective performance in long-term high-temperature and harsh outdoor environments.

It is widely used in exterior wall finishing, industrial equipment surface protection and high-temperature resistant coating engineering.

Building Surface Protection

In the field of building protection, lithium silicate is mainly used for surface hardening, anti-weathering and anti-efflorescence treatment of new and old buildings, stone materials and cement-based building materials.

It can effectively improve the surface compactness and wear resistance of building walls, floor tiles and concrete components, solve common building problems such as surface powdering, sanding and weathering peeling. Its low-shrinkage and high-stability properties ensure no cracking or deformation after long-term use.

Meanwhile, the breathable and transparent protective film formed by lithium silicate will not affect the natural breathing of building substrates, and can effectively resist rain erosion, temperature difference change and atmospheric aging, greatly extending the service life of buildings and stone decorations.

High-performance Refractory Material Industry

Lithium silicate acts as a high-quality inorganic binder in the production of high-performance refractory materials and heat-insulating refractory products.

It features excellent high-temperature resistance, strong bonding strength and stable high-temperature dimensional stability. During the production of refractory bricks, refractory castables and heat-insulating materials, lithium silicate can tightly bond refractory aggregate and powder materials.

After curing and high-temperature sintering, it forms a high-strength and high-temperature resistant integral structure, which avoids cracking and loose falling of refractory materials under long-term high-temperature working conditions.

Benefiting from its stable modulus and uniform liquid state, it has good construction fluidity, which can effectively improve the molding quality and high-temperature service performance of refractory products, and is widely used in high-temperature kilns, furnace bodies and industrial thermal equipment refractory engineering.

Ultra-Low Shrinkage and Excellent Dimensional Stability

With a stable modulus of 4.8–4.9, lithium silicate features an extremely low curing shrinkage rate, which is far superior to sodium silicate and common potassium silicate. During the film-forming and hardening process, it will not cause substrate deformation, surface cracking or peeling.

This excellent dimensional stability ensures the long-term integrity and flatness of cured coatings and concrete reinforced layers, effectively solving the common quality defects of traditional water glass materials and greatly improving the overall construction finish quality.

Outstanding Long-Term Weather and Aging Resistance

Lithium silicate possesses exceptional UV resistance, temperature difference resistance and atmospheric corrosion resistance. After complete curing, it forms a dense and inert inorganic silicon-oxygen network structure, which can resist long-term outdoor exposure, severe cold, high temperature and rainy erosion.

It will not age, fade or pulverize over time, providing durable protection for building substrates, metal equipment and refractory materials, and significantly extending the service life of terminal products and engineering facilities.

High Chemical and Alkaline Stability

Different from conventional alkali silicates, lithium silicate has mild alkalinity and extremely stable chemical properties after curing. It does not undergo secondary chemical reactions with air components or substrate materials, and effectively avoids common problems such as surface efflorescence, alkali precipitation and substrate corrosion.

Its stable structural performance enables it to adapt to various complex industrial and construction environments, maintaining stable protective and reinforcing effects for a long time.

Superior Hardness and Mechanical Properties

Lithium silicate can react with active components on the surface of cement and concrete substrates to generate dense hydrated silicate crystals, which significantly improve the surface hardness, abrasion resistance and compression resistance of the substrate.

The cured lithium silicate film is hard and compact with strong structural toughness, effectively resisting mechanical friction, impact damage and surface wear, making it ideal for high-hardness and wear-resistant engineering scenarios such as industrial concrete floors.

Stable Storage and Construction Adaptability

Industrial liquid lithium silicate with 22°Bé and 4.8–4.9 modulus has uniform texture, no precipitation and no stratification. It features excellent storage stability and long shelf life without deterioration. In terms of construction, it has good water solubility and fluidity, suitable for spraying, rolling and brushing construction methods. It can be directly used without complex dilution and proportioning, greatly simplifying the production and construction process and reducing labor and time costs for downstream enterprises.
