He aha te UV-144 CAS 63843-89-0?

He paura mā ki te kōwhai paku te UV-144, he momo NOR teitei te mahi hei whakaū i te mārama amine ārai, he pai mō te umanga paninga paura. Ka taea e ngā whakaū amine ārai me te whanonga ārai phenolic ārai-wāhanga te whakaiti i te ngatata me te ngaronga o te kanapa, ka roa ake te roa o te ora o ngā kiriata peita.

Tono

He pūmau mārama amine ārai-ārai momo NOR UV-144, he pai mō te umanga paninga paura. Ka taea e ngā pūmau amine ārai-ārai me te whanonga ārai-ārai phenolic ārai-wāhanga te whakaiti i te pakaru me te ngaronga o te kanapa, ka roa ake te roa o te mahi a ngā kiriata peita. I taua wā anō, kei a ia te āhuatanga o te hanga i ngā paninga paura kia waku me te utu, ka whakapai ake i te tere o te paninga paura. Ka whakamahia nuitia i roto i ngā paninga paura, te maitai koiri, ngā paninga motuka, me ētahi atu.
