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.

aminoplastics adhesives, phenolic adhesives, polyurethane adhesives, non-isocyanate polyurethane adhesives (NIPU), acrylic adhesives, epoxy adhesives, renewable resources, environment friendly, partially or totally biobased.

Published Papers
  • Performance of Unidirectional Biocomposite Developed with Piptadeniastrum Africanum Tannin Resin and Urena Lobata Fibers as Reinforcement
  • Abstract The Piptadeniastrum Africanum bark tannin extract was characterized using MALDI TOF, ATR-FT MIR. It was used in the development of a resin with Vachellia nilotica extract as a biohardener. This tannin is consisting of Catechin, Quercetin, Chalcone, Gallocatechin, Epigallocatechin gallate, Epicatechin gallate. The gel time of the resin at natural pH (pH = 5.4) is 660 s and its MOE obtained by thermomechanical analysis is 3909 MPa. The tenacity of Urena lobata fibers were tested, woven into unidirectional mats (UD), and used as reinforcement in the development of biocomposite. The fibers tenacity at 20, 30 and 50 mm lengths are… More

  • An Eco-Friendly Wood Adhesive from Alfalfa Leaf Protein
  • Abstract According to the preparation method commonly used for soy proteinbased adhesives, alfalfa leaf protein was used as the raw material to prepare alfalfa leaf protein-based wood adhesive. Differential scanning calorimetry analyzer (DSC), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) were used to characterize properties of the alfalfa leaf protein-based adhesive in this paper. The results revealed the following: (1) Chemical compositions and chemical structures of the alfalfa leaf protein were basically identical with those of the soy protein, both belonging to spherical proteins with the basis and potential for protein adhesives preparation, and spatial cross-linked network structures would… More

  • Impregnated Paper-Based Decorative Laminates Prepared from Lignin-Substituted Phenolic Resins
  • Abstract High Pressure Laminates (HPL) panels consist of stacks of self-gluing paper sheets soaked with phenol-formaldehyde (PF) resins. An important requirement for such PFs is that they must rapidly penetrate and saturate the paper pores. Partially substituting phenol with bio-based phenolic chemicals like lignin changes the physico-chemical properties of the resin and affects its ability to penetrate the paper. In this study, PF formulations containing different proportions of lignosulfonate and kraft lignin were used to prepare paper-based laminates. The penetration of a Kraft paper sheet was characterized by a recently introduced, new device measuring the conductivity between both sides of the… More

  • 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
