As the wood-based panel industry relies heavily on softwoods, changes in raw material supply may affect adhesive bonding—an essential factor in panel production. This study investigates the bondability of eight wood species (beech, birch, oak, poplar, Douglas fir, larch, pine and spruce) using four adhesives commonly applied in panel manufacturing: polymeric methylene diphenyl diisocyanate (pMDI), modified MDI and two melamine-urea-formaldehyde (MUF) adhesives. Bond strength development was evaluated using the Automated Bonding Evaluation System (ABES). Results were modelled with the Hill function to extract kinetic parameters, and microscopy was used to assess adhesive distribution and bond line failure. Among the adhesives, pMDI showed the highest sensitivity to species variation, while modified MDI was less species dependent. MUF1 showed the most consistent performance and outperformed MUF2 in bond strength development and final strength, likely due to its higher formaldehyde-to-amino group ratio. Beech bonded with pMDI required increased pressing pressure, while larch exhibited the slowest strength development with all adhesives except MUF1. pMDI achieved the highest final strengths, especially with diffuse-porous species. Good compatibility was observed between pine and pMDI, while oak heartwood bonded nearly twice as fast as sapwood when using pMDI. Kinetic modelling revealed distinct curing profiles: MUF adhesives followed a sigmoidal trend, whereas isocyanates showed a hyperbolic pattern. ABES proved effective for evaluating bonding behaviour, though limitations such as adhesive squeeze-out and moisture variation must be considered when translating results to industrial applications.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"146 ","pages":"Article 104230"},"PeriodicalIF":3.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145787914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, the chemical and physical properties of the glass surface, particularly the distinction between the tin and air sides, significantly influence bond strength and long-term joint durability. Therefore, this study systematically investigates the adhesive bonding behaviour of two widely used architectural glass types, soda-lime-silica float glass and low-iron glass, with a focus on differences between their tin-side and air-side surfaces. Experimental results reveal significant variations in bond strength related to both glass type and bonded sides. Low-iron glass consistently outperformed standard float glass, reaching peak shear strengths of 12.65 MPa on the tin-side, whereas the soda-lime-silica float glass showed lower values of 7.60 MPa and 6.32 MPa on its air and tin sides, respectively. To assess the mechanisms underlying these differences, surface characterisation was conducted using water contact angle (WCA) measurements, X-ray photoelectron spectroscopy (XPS), and secondary ion mass spectrometry (SIMS). Enhanced adhesive performance was found to correlate with lower WCA values and higher surface concentrations of non-bridging oxygen (NBO) and negatively charged SiO<sub>2</sub><sup>−</sup> ions. Notably, the tin-side of low-iron glass exhibited the highest NBO content (19.9 %) and the strongest SiO<sub>2</sub><sup>−</sup> signal.
