Scientists in Norway have studied coated wooden claddings and the  influence of nanoparticles on the weathering performance. They carried out accelerated climate aging experiments and cup measurements in order 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 colour 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.

A paper based on this study will appear in the magazine "Progress in Organic Coatings”, Vol. 75, issues 1-2, September-October 2012.
