What is Sodium Silicate Sealant
Sodium Silicate Sealant, often referred to as “liquid glass” sealant, enjoys a significant position in the industrial sealing field due to its unique chemical reaction mechanism and outstanding durability. We are not only experts in the production of Sodium Silicate but also dedicated to providing customers with a complete sealing solution based on Sodium Silicate.
The working principle of sodium silicate sealant
The core value of sodium silicate sealant lies in its unique chemical reaction properties. The liquid sodium silicate penetrates the microscopic pores of the substrate and then reacts with carbon dioxide in the air to form silicic acid gel, which further hardens to form a glass-like silica structure, forming a permanent chemical bond with the substrate. During the sealing process, sodium silicate has two sealing mechanisms. The first is physical filling, where the gel effectively fills pores and micro-cracks. The second is chemical strengthening, as the silica network formed by the curing of sodium silicate integrates with the substrate.
The outstanding characteristics of sodium silicate sealant
Compared with traditional organic sealants, sodium silicate sealant has irreplaceable advantages
· High-temperature resistance: Can withstand a working temperature of up to 1000°C
· Chemical corrosion resistance: Resistant to most acids, solvents and oils
· Zero VOC emissions: Completely free of volatile organic compounds
· Long service life: Lasts for the same duration as the substrate, requiring no frequent maintenance
The specific performance of sodium silicate sealant in application is as follows: The liquid sodium silicate can deeply penetrate, reaching 10mm below the surface of the substrate (such as concrete), and can increase the surface strength by 20-40%. Moreover, the weather resistance of sodium silicate is extremely excellent; it does not age or degrade due to ultraviolet radiation. Sodium silicate is also an environmentally friendly inorganic salt material, non-toxic, non-flammable, and in line with green building standards.
