Chiticoat: biodegradable and sprayable chitin-based barrier coating

Overview

ChitiCoat is an innovative, environmentally friendly coating solution derived from nanofibrillated chitin, a biopolymer extracted from crustacean waste. This single-component coating is enhanced by grafting hydrophobic lipid groups from epoxidized soybean oil onto the chitin surface, resulting in exceptional oxygen and water vapor barrier properties. ChitiCoat is designed as a stable aqueous dispersion, ensuring compatibility with existing industrial spray nozzles, and providing a hydrophobic barrier when dried. Its optical properties are customizable, making it ideal for branding requirements.

Technical specifications

• Material Composition: Nanofibrillated chitin enhanced with hydrophobic lipid groups from epoxidized soybean oil.
• Barrier Performance: Exceeds conventional materials in oxygen and water vapor barrier properties.
• Application: Formulated for spray application, compatible with existing industrial spray systems.
• Recyclability: Avoids chemical crosslinking, maintaining recyclability and solving performance-versus-recyclability challenges.
• Safety: Food-safe, odorless, tasteless with natural antibacterial and antifungal properties.

Technology readiness level

ChitiCoat is currently at a Technology Readiness Level (TRL) of 5. The product has been validated at the laboratory scale, with ongoing efforts to scale up fermentation processes. Plans are in place for pilot-scale validation and independent third-party verification to ensure performance claims are met. Recyclability certification and regulatory approvals are also being pursued to pave the way for full commercial deployment.
