“…The nanoparticle-free compact (REF) underwent major changes in NIR reflectance values after tests for resistance to UV light and to artificial weathering. Therefore, as happened with the total reflectance values, the problem of the increase in the reflectance value in the NIR, after the tests must be related to the composition of the compact and not to the presence of nanoparticles Figures and show the reflectance values in the VIS region and the brightness of the samples to compare these two parameters and understand whether there is a relationship between them.…”

High-pressure laminates (HPLs) are widely utilized in interior applications but may have potential as exterior building facade coatings if suitably enhanced for weatherability. Nanoparticle additives are a promising approach to improving the durability and functionality of HPLs. This study aims to evaluate titanium dioxide (TiO 2 ) and silicon dioxide (SiO 2 ) nanoparticles incorporated into HPLs to determine if they impart properties for durable, functional exterior facades. Methods: HPLs were fabricated with 3.75 wt % TiO 2 and SiO 2 nanoparticles in the surface overlay. Industry-standard EN 438 tests characterized the quality, optical properties, and accelerated aging, including UV radiation, weathering, and thermal shocks. Properties were measured before and after aging to compare versus a standard HPL without nanoparticles. Nanoparticles not only increased initial solar reflectance but also caused color changes. After aging tests, nanoparticles did not sufficiently enhance durability compared to the standard HPL. While initial reflectance improved with nanoparticles, overall weatherability did not, indicating a need to optimize fabrication and nanoparticle selection. Although TiO 2 and SiO 2 nanoparticles increased initial HPL reflectance, the feasibility of durable facade coatings was not conclusively demonstrated. Further research should focus on ideal fabrication methods, nanoparticle types and concentrations, and performance in real-world conditions to facilitate adoption in building facade applications.
