Isicelo:I-UV- 5411 iyi-stanlizer yesithombe esiyingqayizivele esebenza ngempumelelo ezinhlelweni ze-polymeric: ikakhulukazi kuma-polyesters, ama-polyvinyl clorides, ama-styrenics, ama-acrylics, i-polycarbonate, ne-polyvinyl buyal. I-UV- 5411 ichazwa ngokukhethekile ngobubanzi bawo obubanzi be-UV Ablorption, umbala ophansi, ukuguquguquka okuphansi, nokuhlaselwa okuhle kakhulu. Ukuphela okujwayelekile kokuphela kufaka phakathi ukubumba, ishidi, kanye nezinto zokwakha ezikhazimulayo zokukhanyisa ngewindi, uphawu, olwandle kanye nezicelo ze-auto. Izicelo ezikhethekile ze-UV- 5411 zifaka ukumboza (ikakhulukazi ama-themosets lapho ukuguquguquka okuphansi lapho kungukukhathazeka okuphansi), imikhiqizo yezithombe, ama-sealants, kanye nezinto zokwakha i-elastomeric.
