Whakamahi
Ko tenei hua he whakapumau marama me te pai o te mahi, ka kaha ki te whakauru i te rauropi UV o te roangaru 240-340 nm me nga ahuatanga o te tae marama, te kore paitini, te pai o te hototahi, te iti o te nekehanga, te ngawari o te tukatuka me etahi atu Ka taea e ia te tiaki i te polymer ki tona nui, ka awhina ki te whakaiti i te tae. Ka taea hoki te whakaroa i te kowhai me te arai i te ngaro o tana mahi tinana. Kei te whanui te tono ki te PE, PVC, PP, PS, PC karaihe pararopi, polypropylene muka, ethylene-vinyl acetate me etahi atu, he pai rawa te paanga o te rama-marama mo te whakamaroke i te phenol aldehyde, te waipiro o te waipiro me te acname, te polyurethane, te acrylate, te expoxnamee etc.
