Reactive ultraviolet absorber "RUVA-93"
You can obtain a polymer that does not volatilize or leach ultraviolet absorbers, has high safety, and exhibits stable weather resistance for a long period!
"RUVA-93" is a reactive ultraviolet absorber that can easily polymerize with styrene, methacrylic acid esters, acrylonitrile, and others, incorporating ultraviolet-absorbing functional groups into the polymer chain. It allows for the creation of polymers with high safety and long-term stable weather resistance, without the volatilization or leaching of the ultraviolet absorber. It demonstrates its features in applications where previous ultraviolet absorbers did not provide sufficient weather resistance, such as in coatings, films, and textiles. 【Features】 ■ Does not easily volatilize even in high-temperature environments ■ Does not leach from the resin surface ■ Excellent chemical resistance and environmental resistance ■ Maintains long-term weather resistance in thin films and fibers *For more details, please refer to the PDF document or feel free to contact us.
