Abstract (English):
The task of the experiment was to clarify the standard modes of bonding plywood using in their produc-tion low toxic urea-formaldehyde resins, and obtain the required bond strength, as well as statistical anal-ysis of the results of research in order to obtain regression equations. The results showed that the bonding strength of plywood on low toxic resins is lower than on resins with high formaldehyde content. To en-sure the preservation of strength is possible only due to increased consumption of adhesive and duration of bonding.
