摘要

The UV protective coatings were developed by incorporating triazine derivative organic UV stabilizers into inorganic titania particles which were produced by sol-gel method. The objective of this study is to delay the color change of heat-treated wood subjected to outdoor conditions. The protective coatings were prepared in air at room temperature. The coatings were not further treated thermally after their application to heat-sensitive materials. Coatings were applied to heat-treated jack pine wood. Subsequently, accelerated aging tests were carried out using coated and uncoated jack pine samples. The color change of the wood samples was studied, and the results were compared. Also, the morphological analyses were done using XPS after having weathered the wood at different times.
