Lithium Silicate Liquid
Lithium Silicate is a high-performance inorganic silicate solution widely used for concrete densification and surface treatment. It penetrates deeply into concrete surfaces and chemically reacts with calcium hydroxide to form a dense and durable structure. This process significantly improves surface hardness, abrasion resistance, and dust-proof performance.
Cas No: 12627-14-4 HS Code: 2839.9000
Chemical formula: Li₂O·SiO₂·H₂O
Molecular Weight: 89.97 Melting Point: 976℃
Lithium Silicate is a high-performance inorganic silicate solution widely used for concrete densification and surface treatment. It penetrates deeply into concrete surfaces and chemically reacts with calcium hydroxide to form a dense and durable structure. This process significantly improves surface hardness, abrasion resistance, and dust-proof performance.
Compared with traditional sodium or potassium silicates, lithium silicate offers faster penetration, better durability, and long-term protection. It is widely used in modern concrete flooring systems for industrial facilities, warehouses, parking garages, and commercial buildings.
