Wood and other lignocellulosic composites are growing in use and the adhesives used in these composites plays a major part in how these composites perform in terms of mechanical and wet exposure properties. The largest wood composites markets are for panel products like Oriented Strand Board (OSB), Plywood, Particleboard (PB) and Medium and High-Density fiberboards (MDF and HDF). Another growing area that requires high performance adhesives is Cross Laminated Timber (CLT) which is a large-scale, prefabricated, solid engineered wood panel used in building construction. This webinar will discuss the complex nature of wood adhesion and explore the use of isocyanate and polyurethane adhesives as high performance adhesives for wood composites. The mechanism of how isocyanate and polyurethane adhesives work will be discussed along with important factors to consider when using these adhesives to make wood and lignocellulosic composites. The presentation topics include: An introduction to adhesive considerations, The unique nature of wood as a bonding surface, The chemistry of isocyanates and polyurethanes, Mechanism of isocyanate and polyurethane adhesion, Summary of important concepts, Questions and discussionss
