Sustainability has increasingly become a cornerstone of the chemical industry. Sustainability metrics include low volatile organic compound (VOC) content, high efficiency, low toxicity, low energy requirements, minimal waste, recyclability, durability, and the use of renewable feedstocks. Powder coatings are well known for zero VOCs, efficient utilization, low toxicity, and recyclability.

Powder coating technologists have recently ventured into the use of renewable feedstocks to synthesize binder systems. Bio-based compounds have been successfully used to produce highly sustainable powder coatings. This review presents recent research on new binder components designed for powder coatings, including: (poly(limonene carbonate)s; polyester resins; polyamide resins; and crosslinking agents (urethane-acrylates, blocked polyisocyanates). The applications of bio-based materials in powder coatings are also highlighted in this review.
