| Abstract: | The physical properties of six type particleboards bonded with different formaldehydebased resins were tested. arer wetting and redrying, Uiree PF bonded boards retained much higher pro portion of their initial dry strength than the boards bonded with resins containing urea. The strength lossis the results of mechanical forces, caused by particle movement, breaking adhesive bonds. |
