Sol-gel coatings are thin, uniform layers produced by converting a liquid solution (sol) into a solid (gel). This process enables precise control of coating structure and performance.
Key properties:
- Corrosion resistance – strong protection of metals in aggressive environments
- Thermal stability – reliable performance at elevated temperatures
- Optical clarity – high transparency for lenses, displays, and optical components
- Mechanical durability – resistance to wear, scratches, and abrasion
- Custom functionality – hydrophobic, anti-reflective, or non-stick surfaces
- Environmentally friendly – low-temperature, water-based processing, PFAS-free options
Applications:
- Food industry – non-stick, heat-resistant coatings for cookware and industrial bakeware, safe for food contact
- Optical systems – lenses, mirrors, and displays with anti-reflective and transparent coatings
- Protective layers – corrosion and wear protection for metals and alloys
- Biomedical devices – biocompatible coatings for implants and medical instruments
- Electronics – insulating and protective coatings for sensors, semiconductors, and micro-components
