Summary

The field of adhesives is in constant and rapid evolution with considerable novelties been published constantly. In particular the strong tred at present is to develop alternatives to synthetic oil-derived adhesives. A number of different trends are present on this front. Different approaches can be noticed such as (i) adhesives where a renewable biosourced material is used as partial but consistent substitution of an oil derived material leading to hybrid but definetely more enviroment friendly adhesives, and (ii) adhesives based totally or partially on synthesis materials but these being exclusively derived from totally biosourced renewable materials, and (iii) Adhesives based on totally renewable materials, modified or unmodified. All these three trends are strongly represented at present.

  • No-Aldehydes Glucose/Sucrose-Triacetin-Diamine Wood Adhesives for Particleboard
  • Abstract A three reagents adhesive system for wood particleboards not containing any aldehyde was developed by the reaction of glucose or sucrose with triacetin (glycerin triacetate) and with hexamethylene diamine. The system was found to be based on the mix of three reactions, namely the reaction of (i) glucose with triacetin, (ii) of the diamine with triacetin, and (iii) of glucose with the diamine. The chemical species formed were identified by Matrix Assisted Laser Desorption Ionization Time of Flight (MALDI-ToF) mass spectrometry. Wood particleboard panels were prepared with this adhesive system and gave good internal bond (IB) strength results suitable for… More
