Polyester Technology

Understanding polyester technology in powder coatings

At the core of powder coatings, polyester technology is a vital element. Essentially, polyester in powder coatings refers to a class of resins known for their superior resistance to UV radiation, providing a durable and aesthetically pleasing finish, making them suitable for prolonged exposure to sunlight. They also perform impressively in indoor environments. 

Polyesters can be cured thanks to different crosslinkers depending of the regions and the needed properties:

  • TGIC Polyesters 
  • TGIC-free Polyesters 
  • Radiation cured Polyesters (peroxide or UV curing) 


Let's explore further this technology, its application, and the unique benefits it contributes to our product range. 


Advantages of polyester technology


Polyester technology in powder coatings offers several compelling advantages, making it a preferred choice for a variety of applications: 

  • Weather Resistance: It's exceptionally resistant to weather conditions thanks to its resistance to UV radiation, making it ideal for outdoor use and ensuring the color and finish remains consistent over the years.  A wide range of exterior durability levels can be achieved with polyester powder coatings. 
  • Versatile Application: It can be efficiently applied to both steel and aluminium substrates and offers extended possibilities of colors and finishes
