Simultaneous confocal laser scanning microscopy (CLSM) observation of melamine–urea–formaldehyde resin and pMDI wood adhesives penetrating plywood

Journal of Wood Science
Abstract Wood absorbs carbon dioxide from the atmosphere, and by being converted into wood-based materials, stores carbon in the long term, thereby contributing to the mitigation of global warming. Wood production relies on adhesives, making a detailed understanding of the adhesive interface essential to ensure performance.
