I-UV 328 iyisishutheli se-UV esingu-290-400nm esinomphumela omuhle wokusimamisa ukukhanya-nge-photochemistry; umkhiqizo unokumunca okuqinile kokukhanya kwe-ultraviolet, umbala wokuqala ophansi embala womkhiqizo, uncibilika kalula ku-plasticizer kanye nohlelo lwe-monomer, uguquguquke kancane, futhi unokuhambisana okuhle nezinto eziningi eziyisisekelo; emikhiqizweni yangaphandle, ingasetshenziswa ne-phenolic antioxidant kanye ne-phosphate ester antioxidant kanye ne-amine photostabilizer evinjiwe.
Isetshenziswa kakhulu ku-polyolefin, i-PVC, i-HDPE, i-styrene eyodwa kanye ne-copolymer, i-ABS, i-acrylic polymer, i-polyester engasetshenzisiwe, i-polythermoplastic polyamine, i-polyurethane epholisayo, i-polyacetal, i-PVB (i-polyvinyl butyaldehyde), i-epoxy ne-polyurethane uhlelo lwezingxenye ezimbili, i-alcohol acrylic acid uhlelo lokupenda kazibuthe; ibuye isetshenziswe ezimbotsheni zezimoto, ezimbotsheni zezimboni, ezifakwe ngokhuni.
Engeza inani: 1.0-3.0%, inani elithile elengeziwe linqunywa ngokuya ngokuhlolwa kwesicelo sekhasimende.
Ipakishwe esikhwameni sephepha se-kraft esingu-20Kg/25Kg noma ibhokisi.
Gwema ukukhanya kwelanga, ukukhanya okuphezulu, umswakama, nezinzinzisi zokukhanya eziqukethe izakhi zesulfure noma ze-halogen. Idinga ukugcinwa endaweni evalekile, yomile futhi kude nokukhanya.
