“…Adhesives such as moisture-curing adhesives require moisture to start the curing process. The moisture in the environment or on the substrate surface reacts with specific chemical groups in the glue, such as isocyanate or silane groups, to form cross-links and create a strong bond [41]. The strength of adhesion was likely affected by the moisture profile in the conditioned and natural wet samples, which decreased its performance.…”

Appraising and protecting forests requires a management plan and the creation of innovative products for the market. The development of the green gluing technique could add value to native timber. However, there is a lack of knowledge concerning the response and the productive process of Nothofagus species using this technique. This work investigated the viability of implementing the green gluing method using three types of Nothofagus. Wood pieces were made using a one-component polyurethane adhesive. Delamination, shear tests, morphological characterization, and bond line thickness analysis tested their capacity. The results showed a variable response depending on the Nothofagus type, where the surface treatment could improve the green gluing performance. The findings highlight the relevance of increasing knowledge about the essayed species and their preparation to maintain their natural moisture condition.
