Coated wooden claddings and the influence of nanoparticles on the weathering performance

Fufa, Selamawit Mamo / Jelle, Bjoern Petter / Hovde, Per Jostein / Roervik, Per Martin

Accelerated climate aging experiments and cup measurements have been performed to investigate the effect of adding TiO₂ nanoparticles and nanoclay to acrylic stain coatings against the influence of weathering. The coated specimens resistance toward solar radiation and water spray was evaluated by the discoloration rate from visual assessment and color analysis and by the chemical changes observed by Fourier transform infrared spectroscopy. Furthermore water vapor resistance was examined by the cup measurements. The nanomaterial containing coatings provided in general better protection against the artificial aging than the unmodified coating, showing the nanomaterials may have a natural place in coatings for protection of wood.
