Polyhedral oligomeric silsesquioxanes as titanium dioxide surface modifiers for transparent acrylic UV blocking hybrid coating

Effect of Additives on Weathering

“…132 Transparent acrylic UV blocking hybrid coating made use of titanium dioxide with surface modification with polyhedral oligomeric silsesquioxanes. 133 Surface modification improved TiO 2 dispersion, which, in turn, offered better protection against UV exposure. 133 TiO 2 coatings were developed for improvement of protection of cultural heritage.…”

Weathering of Compounded Products

“…They provide evidence to support this conclusion and describe a method of measuring residual stress in the coating. 611 TiO 2 surface has limited compatibility with polymers what can result in non-stable dispersions. Fracture energy, film thickness, stress level, and weathering time were determined for automotive clearcoats.…”

Enhanced mechanical properties and anti-hydrothermal ageing behaviors of unsaturated polyester composites by carbon fibers interfaced with POSS

“…SO 1450 can be used for surface modification of fillers, such as metal oxides, and other materials. It is also effective as an additive to thermoplastics and thermoset polymers for improving the moisture resistance and process-ability [24,25]. SO 1450 possesses several distinct advantages (providing thermal and chemical stability, enhanced compatibility with the hosting polymer matrix or with the functional groups for chemically reacting with a polymer matrix) over traditional surface modifiers like silanes due to its hybrid molecule.…”
