PET-upcycled and Biobased Hyperbranched Polyesters for Selfhealable and Flame-retardant Powder Coatings

Key Points

• The aim is to develop selfhealable and flame-retardant polyester powder coatings using upcycled PET and biobased materials.
• Utilized upcycled PET and biobased components for polyester synthesis.
• Assessed selfhealing properties and flame retardancy through various testing methods.
• Evaluated compliance with environmental standards and VOC emissions.
• The developed coatings exhibited effective selfhealing properties.
• Significant flame-retardant characteristics were observed.
• Materials met regulatory standards for environmental safety.
