Enhancing the Quality of Industrial Floor Coatings by Optimizing DBU Levels in Polyurethane Mixtures Abstract Polyurethane (PU) coatings are widely used in industrial flooring due to their durability, chemical resistance, and ease of application. However, the performance of these coatings can be significantly influenced by the levels of additives such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). This study...
