Yintoni UV-144 CAS 63843-89-0?

I-UV-144 emhlophe ukuya kumgubo omthubi kancinane, ukusebenza okuphezulu OKANYE uhlobo luthintele isizinzi sokukhanya se-amine, esilungele ushishino lokugquma umgubo. Ukuthintelwa kwe-amine stabilizers kunye nokuziphatha okuthintelweyo kwe-phenolic antioxidant kunokunciphisa ukuqhekeka kunye nokulahleka kweglosi, bandise kakhulu ubomi benkonzo yeefilimu zepeyinti.

Isicelo

I-UV-144 ephezulu yokusebenza NOR uhlobo luthintele i-amine light stabilizer, ifanelekile kwishishini lokugquma umgubo. Ukuthintelwa kwe-amine stabilizers kunye nokuziphatha okuthintelweyo kwe-phenolic antioxidant kunokunciphisa ukuqhekeka kunye nokulahleka kweglosi, bandise kakhulu ubomi benkonzo yeefilimu zepeyinti. Ngelo xesha, inepropati yokwenza i-powder coatings frictional and charged, iphucula izinga lokutyalwa kwepowder. Isetyenziswa kakhulu kwiingubo zomgubo, intsimbi ye-coil, i-automotive coatings, njl.
