What is the role of acrylic powder coatings


Acrylic powder coatings have excellent decorative, weather resistance, and stain resistance, and high surface hardness. Good flexibility. But the price is high and the corrosion resistance is poor. Therefore, European countries generally use pure polyester powder (carboxyl-containing resin, cured with TGIC);(hydroxyl-containing polyester resin cured with isocyanate) for weather-resistant powder coatings.
