Hydroxymethylfurfural: A key to increased reactivity and performance of fructose-based adhesives for particle boards

There is a push towards the use of renewable adhesives in particle board manufacturing industry. A remaining barrier for successful implementation carbohydrate-based necessity rapid cure behavior at lower temperatures (105–120 °C). The aim this work was to study effect highly reactive, bio-based 5-Hydroxymethylfurfural (HMF) on speed fructose-bishexamethylenetriamine (BHMT) adhesive. technological suitability these intended application boards done by combining adhesive characterization with thermal analysis and tensile shear strength development. Overall, HMF had strong, positive reactivity performance fructose-based adhesives, especially hot-press temperatures. development fructose/HMF/BHMT comparable commercial, fossil-based urea-formaldehyde resin 120 °C. sufficient 5.0 ± 0.3 N/mm2 reached after press times as low 30 s 6.2 0.1 pressing 150 105 This suggests fructose-HMF-BHMT have such are promising cleaner production boards. Their among best previously reported HMF-based adhesives.
