What are vacuum color coatings typically made from?

Vacuum color coatings are typically made from inorganic materials due to their stability, durability, and ability to provide a wide range of colors and effects. Inorganic materials such as metal oxides, nitrides, and sulfides are commonly used in vacuum coating processes because they can form strong bonds with the substrate surface and possess high resistance to environmental factors such as UV radiation, moisture, and temperature changes. This makes them suitable for applications such as reflective coatings in optics, protective coatings for electronics, and decorative finishes in various industries.

While polymers, organic dyes, and ceramics have their own applications in coatings, they do not possess the same level of performance and stability in vacuum color coating processes as inorganic materials. Polymers may not withstand high temperatures, organic dyes can degrade under UV exposure, and while ceramics can be durable, they often do not provide the same versatility in color and finish that inorganic compounds offer. Thus, the choice of inorganic materials is crucial for achieving effective vacuum color coatings.
