DETERMINATION OF BONDING PERFORMANCES OF MODIFIED POLYVINYLACETATE (PVAc) AND KLEBIT 303 (K.303) ADHESIVES IN DIFFERENT HOT-SURROUNDINGS
In this study, performances of woods bonded with polyvinylacetate (PVAc) and Klebit 303 (K.303) thermoplastics glues and PVAc+UF and K.303+UF thermoset glues that were modified with Urea-fomaldehyde were investiguted at various temperatures.

| Summary: | In this study, performances of woods bonded with polyvinylacetate (PVAc) and Klebit 303 (K.303) thermoplastics glues and PVAc+UF and K.303+UF thermoset glues that were modified with Urea-fomaldehyde were investiguted at various temperatures. In total, 320 experimental samples were investigated at various temperatures which were prepared from pine wood (Pinus sylvestris L.), beech wood (Fagus orientalis L.) and were bonded with PVAc, K.303, PVAc+UF, K.303+UF glues. After these experimental samples were held for two hours at 20 °C, 40 °C, 60 °C, 80 °C temperature, tensile test was applied according TS EN 205. It was found that the adhesion performance of unmodified PVAc and K.303 bonded samples decreases when temperature increases, moreover, this retuction is smaller in samples bonded with PVAc+UF and K.303+UF in comparison to unmodified glues and in samples of beech wood in comparison to pine wood. |
