Epoxy polyester powder coating is a type of powder coating that combines the properties of both epoxy and polyester resins. This coating is used to protect and decorate a wide range of materials, typically metals, and is popular in various industrial and architectural applications. Here’s an overview of its features and benefits:
Epoxy polyester powder coatings offer excellent protection against corrosion, making them ideal for metal substrates exposed to harsh environments. They are resistant to a range of chemicals, which adds to their durability in industrial settings.
Available in a wide range of colors, textures, and finishes, including matte, gloss, and satin. Powder coating provides a smooth, even finish without runs or drips.
Unlike liquid coatings, powder coatings contain minimal volatile organic compounds (VOCs), making them more environmentally friendly. Any overspray can be collected and reused, reducing waste.
i.Electrostatic Spray: Powder coating is applied using
an electrostatic spray gun, where the powder particles are charged and adhere to the
grounded metal surface.
ii. Curing: After application, the coated item is heated in an oven, where
the powder melts
and forms a continuous, durable film.
Epoxy polyester coatings can withstand moderate temperatures, although they might not be suitable for extremely high-temperature environments.
