The objective of the research was to develop an adhesive in which part of the synthetic resin is replaced by liquefied wood. A synthetic phenol-formaldehyde (PF) adhesive, mixed with different proportions of liquefied wood, was used for the bonding of two beech wood lamellas. Liquefied wood made from poplar was added in different proportions, ranging from 0 % to 100 %, with increments of 25 %. It was found that the bond shear strength of the dry specimens increased if 25 % of the PF adhesive was replaced by liquefied wood, but decreased if a higher proportion of liquefied wood was used.

Abundant amounts of plants and their products can be found in the nature. They can be used as potential material to produce wood adhesives because of their ability to bond different materials. Furthermore, their environmental pollution is minimal, volatile organic compound emission is low, they are renewable and affordable in their basic form. Results of the studies and efforts to develop wood adhesives based on soy, carbohydrates from natural sources and other plant materials are presented in this article.
