Applicatio

UV-329 est stabilisator photoelectricus singularis, efficax in variis systematibus polymericis: praesertim in polyesteris, polyvinylchloridis, styrenis, acrylicis, polycarbonatis, et polyvinylbutyal. UV-329 praecipue notus est propter latam absorptionem UV, colorem humilem, volatilitatem humilem, et solubilitatem excellentem. Usus finales typici includunt formas, laminas, et materias vitreas ad illuminationem fenestrarum, inscriptiones, applicationes marinas et autocineticas. Applicationes speciales pro UV-5411 includunt tunicas (praesertim themosets ubi volatilitas humilis cura est), producta photographica, obturamenta, et materias elastomericas.
