The use and significance of adhesives in various industries are explored, highlighting the growth of the adhesive market and the crucial role of time in adhesive bonding. The composition of adhesives, particularly polyurethane adhesives (PUR), is detailed, emphasizing their sensitivity to environmental factors, like moisture and UV radiation. Various factors influencing adhesive properties, such as reactivity and curing-induced shrinkage, are discussed, along with the importance of catalysts in adjusting reaction rates. Onecomponent moisture-curable PUR adhesives are presented as versatile and continually improving alternatives in structural adhesive applications. The research's focus was to investigate the curing speed of Sikaflex-252 1-component PUR structural adhesive under different conditions, including room temperature, room temperature with ~30 % humidity, and room temperature with ~100 % humidity.
