Iron-Based Polyurethane Metal Catalysts: Development and Applications in Polyurethane Systems Abstract: Polyurethane (PU) systems are ubiquitous in modern materials science, finding applications in diverse fields such as coatings, adhesives, elastomers, and foams. The efficiency of PU synthesis, primarily driven by the reaction between isocyanates and polyols, is often enhanced through the use of catalysts. Traditional...
