Abstract [eng] |
Wood is aesthetically pleasing and hence there is great demand for finishing systems not to mask wood’s color and texture. Unfortunately, clear coatings used on wood outdoors fail within a short time. The performance of clear coatings on wood can be enhanced by modifying the clear coating with inorganic metal oxide nanoparticles. The main objective of this research is to reduce UV transmittance through water-based clear acrylic and polyurethane wood coatings, using CeO2 nanoparticles. The results have shown that increasing concentration of CeO2 nanoparticles in the coating, results in increasing coating absorption of UV radiation. However, increased CeO2 concentration causes yellowing of coatings. Despite the fact that CeO2 gives yellow undertone for coating, it keeps durability and UV resistance. |
