AB The paper includes results of research work dealing with the study of the effect of mixing the traditional urea-formaldehyde adhesive Kronores CB 1100 D and the urea-formaldehyde adhesive Kronores CB 1200 D characterised by increased reactivity for selected physical and mechanical properties of particleboards, the content of free formaldehyde and productivity of the production line of particleboards. Within the research, other potential factors affecting properties of particleboards were also studied. Present adhesive prescriptions (1) and five experimental prescriptions were evaluated. In conclusion, optimum prescriptions were determined fulfilling the CSN EN 312 standard requirements for physical and mechanical properties of particleboards of P 2 class and a pressing factor was defined substantially affecting the rate of a production line or production productivity.
