UV 292 CAS 82919-37-7 yog dab tsi?

UV 292 yog lub teeb ua kua ua kua uas tuaj yeem txuas ntxiv lub sijhawm tawm sab nraud ntawm ntau yam yas thiab txheej txheej. Thaum lub sijhawm ua haujlwm, nws tsis tsim cov ntxhiab tsw nrog polymers lossis cuam tshuam rau cov xim qub ntawm cov khoom. Nws tsis yooj yim volatile thaum lub sij hawm kub ua hauj lwm thiab muaj superior polymer compatibility.

UV 292 yog lub teeb stabilizer tsim los ntawm kev sib xyaw ntawm ob esters, uas muaj kev sib koom ua ke nrog benzotriazole UV absorbers thiab tuaj yeem tiv thaiv cov coatings los ntawm tawg thiab nto tev tawm hauv qab hnub ci.

Daim ntawv thov

UV 292 feem ntau yog siv rau hauv cov organic polymers xws li polyethylene, PVC, PVB, ABS resin, polyester, thiab polyurethane. Tshwj xeeb tshaj yog haum rau polyurethane, raws li lub teeb stabilizer 292 muaj zoo solubility nyob rau hauv cov kuab tshuaj.

UV 292 yog qhov tsim nyog rau cov txheej txheem tsheb thiab cov txheej txheem kev lag luam. Ntoo xim, lub teeb hardening industrial coatings, PU resin, adhesives thiab lwm yam yas.

UV 292 muaj cov nyhuv synergistic zoo thaum siv ua ke nrog benzotriazole hom UV absorbers, uas tuaj yeem txhim kho huab cua tsis kam ntawm cov khoom, zoo dua li siv UV absorbers ib leeg. Los ntawm kev ntxiv cov dispersants tsim nyog, Lub Teeb stabilizer 292 tuaj yeem ua tau zoo rau cov txheej txheem dej.
