Polyester powder coating is a coating material generally used to cover and protect metal surfaces. This type of powder coating contains polymeric resin and is usually based on polyester resin. Polyester powder paints are applied by electrostatic spraying method and then hardened by the effect of temperature.
Properties of polyester powder coatings may include:
1. Durability:
Polyester powder coatings are resistant to external influences and generally provide long-lasting coatings.
2. Color Options:
Polyester powder coatings offer a wide range of colors, making them suitable for decorative or marking purposes.
3. Chemical Resistance:
These types of powder coatings are generally resistant to chemicals, so they are suitable for use in industrial environments.
4. UV Resistance:
It can be resistant to fading when exposed to sunlight, which can be advantageous for outdoor applications.
5. Electrostatic Spraying:
Polyester powder coatings are applied to metal surfaces using an electrostatic charge. This ensures that the powder adheres properly to the surface.
Polyester powder coatings are often used in various applications such as metal furniture, automotive parts, bicycle frames, rail systems. Application and curing processes may vary depending on the requirements of specific products and manufacturer's instructions.
