Polyesters are the most commonly used powders and offer great value for money. The two most widely used types of polyester powder: TGIC (tri glycidyl isocyanurate) and non-TGIC, which is also known as TGIC-free or sometimes a ‘Primid’. Both TGIC and TGIC-free polyesters offer good mechanical resistance, including great flexibility and impact resistance, and good chemical resistance.
advantage
• excellent weathering resistance
• excellent mechanical properties
• high flexibility
• good leveling properties
• good storage stability
• excellent optical appearance
For applications that involve items permanently outside, super durable polyester may be desirable to increase durability and wearability.
