Siv
UV5151 yog cov kua sib xyaw ua ke ntawm hydrophilic 2-(2-hydroxyphenyl)-benzotriazole UV absorber (UVA) thiab ib qho yooj yim hindered amine light stabilizer (HALS). Nws tau tsim los ua kom tau raws li cov nqi siab / kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov txheej txheem sab nraud dej thiab cov kuab tshuaj borne kev lag luam thiab kho kom zoo nkauj. Qhov dav UV absorbance ntawm UVA siv ua rau nws haum rau ntau yam txheej txheem rau ntoo, yas thiab hlau. Kev sib xyaw ua ke muab kev tiv thaiv txheej txheem zoo tshaj plaws tiv thaiv kev txo qis gloss, tawg, blistering, delamination thiab hloov xim thiab muab kev tiv thaiv substrate tag nrho.
