- Description: Applied as a dry powder that is cured under heat to form a robust, protective layer. Known for its resistance to chipping, scratching, and fading.
- Applications: Ideal for metal surfaces in industrial, automotive, and architectural contexts.
- Electroplated Coatings:
- Description: Metal coatings applied through electroplating, offering corrosion resistance and enhanced appearance.
- Applications: Used in automotive parts, electronic components, and decorative finishes.
- Organic Coatings:
- Description: Paints and varnishes composed of organic compounds that offer decorative and protective finishes.
- Applications: Common in residential, commercial, and industrial settings for various surfaces.
- Ceramic Coatings:
- Description: Hard, protective coatings made from ceramic materials, providing high-temperature resistance and durability.
- Applications: Applied to automotive parts, machinery, and industrial equipment.
Innovations in Spraying Technology
Spraying technology has evolved significantly, offering various methods to apply non-conversion coatings effectively. Here’s how different spraying techniques contribute to achieving optimal results:
