Functional coatings are specialized layers applied to surfaces to enhance their properties and performance. These coatings can provide benefits such as corrosion resistance, anti-fogging, or self-cleaning capabilities. They are commonly used in various industries, including automotive, electronics, and construction, to improve the durability and functionality of products. These coatings can be made from different materials, including polymers, ceramics, and metals. Examples of functional coatings include anti-reflective coatings for glasses, hydrophobic coatings for textiles, and biocidal coatings for medical devices. By tailoring these coatings, manufacturers can meet specific needs and improve the overall user experience.
