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.

Implication

Research investigates selfhealability and flame-retardancy in biobased polyester coatings, indicating advancements in sustainable materials.

Abstract

Although polyester powder coatings are widely utilized due to their volatile organic compound (VOC)-free processing, they still exhibit deficiencies in balancing sustainable carbon sources, regulatory compliance, in-service repair and fire...
