Abstract

The development of high-performing, safe, and sustainable epoxy systems is critical for modern industrial applications, particularly in sectors where labeling, safety, and regulatory compliance are essential. This study presents two novel ultra-low emission epoxy hardeners designed to minimize volatile organic compound emissions and offer a beneficial safety profile, while maintaining excellent adhesion, fast Shore D hardness development and high carbamation resistance. The hardener formulations were optimized using modified polyamine components, resulting in a system with significantly reduced emissions compared to conventional alternatives. Comprehensive analytical techniques and coating performance tests according to established standards were employed to assess the curing behavior and mechanical performance. The results demonstrate that the developed hardeners show excellent coating properties without compromising good labeling, offering a practical solution for industrial epoxy applications meeting required ultra-low emission properties.
