Hydroxymethylfurfural and its Derivatives: Potential Key Reactants in Adhesives

5‐Hydroxymethylfurfural (HMF) is a promising bio‐derived platform chemical with a broad scope of application, for example, in the production of solvents, fuels, polymers, or adhesives. The wood and foundry industries are among the largest adhesive users and currently both rely to a large extent on the use of fossil‐based binders, such as by using formaldehyde as a crosslinker in many commercial adhesive systems. The industry is thus looking for suitable alternatives to replace fossil‐based chemicals. HMF and its derivatives are considered to be key renewable reactants in adhesive systems. The core of this Review is the critical evaluation of the potential of HMF and its derivatives in adhesive systems. The technological performance was assessed in the fields of wood‐based materials, sand casting and composites. As an overall conclusion, HMF and its derivatives have a high application potential in alternative adhesives. Clearly, further research is needed to improve the performance and produce economically competitive adhesives. Sticks like glue: This Review critically assesses the role of 5‐hydroxymethylfurfural (HMF) and its derivatives as renewable key reactants in adhesives. Application fields range from wood‐based materials, sand casting, and composites. The technological performance of many HMF‐based adhesives reaches the minimum requirements, but further research on economically feasible HMF‐based resins is needed.
