Using water as a solvent to meet high regulatory demands.
Polyester resins are the most commonly used for powder coatings and are a common first choice for many applications. The two most widely used types of polyester powder coatings are TGIC (tri glycidyl isocyanurate) and TGIC-free, mostly based on hydroxy alkyl amide (HAA) hardeners “Primid®”. Both TGIC and Primid® polyesters offer good mechanical and chemical resistance, also including great flexibility and impact resistance. Polyester powder coatings show versatile all-around properties. Both TGIC and Primid® polyester powder coating also provides good overbake resistance to yellowing, which renders them easy to use. A particular advantage of polyester powder coatings is that they offer excellent UV resistance, making them great choices for all interior and many exterior applications. Another huge advantage of polyester powder coating is the enormous variety of applicable colors, gloss levels, and special effects. The possibilities are nearly infinite!
