The Effect of Microwave Radiation on the Technological Properties of Urea–Formaldehyde Glue

The results of studies on the effect of microwave radiation treatment on the technological properties of the solution of Dorus FU 406/1 urea–formaldehyde glue. It has been found that a change in the specific power and duration of microwave treatment of the glue solution significantly affects changes in its alkaline–acid equilibrium of the medium towards a decrease in pH and a reduction in the duration of gelation at 100°C and at that does not exert any significant effect on the viability of the working glue solution.
