Study on the effect of urea addition to urea-formaldehyde adhesive on physical and mechanical properties of poplar particleboard

In this research, the effect of increasing content of urea to urea-formaldehyde adhesive on physical and mechanical properties of poplar wood particleboard was investigated. The content of urea added to the adhesive four levels (zero, 4.1, 8.2 and 16 % based on the solid content of adhesive) and tw...
