Sol-gel coatings are a type of material formed through the sol-gel process, which is a chemical synthesis method involving the formation of solid materials from a liquid precursor. The sol-gel process involves two key steps:
Sol Formation: The precursor is mixed with a solvent to form a sol, which is a colloidal suspension of particles.
Gelation: The sol undergoes chemical reactions to form a gel network that is then applied to a surface as a thin film.
The coating can be applied through various techniques, including dip-coating, spray-coating, spin-coating, and brushing. The result is a coating that provides excellent adhesion, durability, and resistance to a range of environmental factors.
The global sol-gel coatings market has been experiencing steady growth, driven by the increasing demand for advanced materials in various applications.
