Application of lithium silicate in coatings

lithium silicate  is a compound formed by the structure and formation of metallic lithium and silicate radicals. The trade name is lithium water glass. Most of them use the lithium hydroxide method to react sodium silicate with sulfuric acid to generate hydrated silicic acid and sodium sulfate. The hydrated silicic acid reacts with lithium hydroxide to generate lithium silicate and water to prepare lithium silicate products.

1. Increase coating hardness and wear resistance

Lithium silicate is an effective additive in paint manufacturing, which can improve the hardness and wear resistance of coating films. Lithium silicate works together with other ingredients in the coating to increase the hardness of the coating film, improve its wear resistance, and greatly extend the service life of the coating.

2. Improve corrosion resistance

Lithium silicate can also be used to improve the corrosion resistance of coatings, especially for metal coatings. Lithium silicate can work with other ingredients in the paint to form a protective layer, which can effectively prevent oxidation, rust and other phenomena of the metal coating and extend the service life of the coating.

3. Improve paint emulsification

Lithium silicate can also be used to improve the emulsification of paints. Particles in the paint are prone to settling, affecting the uniformity and quality of the coating. Adding lithium silicate can effectively improve the emulsification of the paint, prevent the occurrence of layering, and make the coating more uniform.

4. Prevent paint settlement

Lithium silicate also prevents the settling of particles in the paint. There are often some solid and particulate matter in paint, which can easily lead to the precipitation of particulate matter and affect the performance of the paint. The addition of lithium silicate can effectively prevent the precipitation of particulate matter and make the coating more viscous and uniform.

In conclusion, lithium silicate can bring multiple benefits as an important additive in coating production. It can improve the hardness and wear resistance of the coating, improve the emulsification of the coating and prevent precipitation. It can also improve the corrosion resistance of the coating and protect the coating from damage. However, you need to pay attention to the dosage when using lithium silicate. Excessive use may have adverse effects on the performance of the coating.
