Why are inorganic coatings such as silica sol so important

According to people's habits, inorganic coatings generally refer to a type of coating whose

main base material is inorganic materials. Here, the meaning of the main base material isthat some inorganic base materials (such as silica sol) must add a certain amount of organic base material compound modification to make up for the lack of performance when preparing coatings. Inorganic coatings are one of many inorganic materials. Even as far as coatings are concerned, inorganic coatings only occupy a small proportion, but they should be highly valued by people.

First of all, the base materials of inorganic coatings are often directly drawn from nature, sothe sources are very rich. For example, coating base materials such as silica sol and silicatesolution are mainly derived from quartz ore, which is an extremely abundant material in nature.

Secondly, compared with some organic coating base materials, the production and use of inorganic coating base materials have less environmental pollution. Most of the products use water as the dispersion medium, and have no adverse effects on the environment and health.

Third, the aging resistance and certain physical and chemical properties of inorganic coatings are difficult to achieve for most organic coatings with the same production cost, so they have better technical and economic performance.

Fourth, most inorganic coatings are alkaline, which is more suitable for application on bases such as cement and lime sand, which are also alkaline, and can chemically react with lime in these base materials to form calcium silicate crystals, which can be integrated with the base , so its adhesion is particularly good.
