ʻO UV-327 he pauka melemele ʻeleʻele i hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka methanol, ethanol, a me toluene.He wahi heheʻe kiʻekiʻe kona, kūpono ia no nā noi e koi ana i ke kū'ē i nā mahana kiʻekiʻe.
ʻO kekahi o nā waiwai koʻikoʻi o UV-327 ʻo kona hiki ke hoʻopaʻa i ka radiation UV ma ka laulā o 290-400 nm.Hiki iā ia ke pale pono i nā mea mai nā hopena ʻino o ke kukui UV.Hana ʻia ʻo UV-327 ma ka ʻohi ʻana i nā radical manuahi a me nā ʻano oxygen reactive i hana ʻia e ka radiation UV, no laila e pale ai i ka hōʻino ʻana a me ka mālama ʻana i nā waiwai kino o nā mea.

Plastics and Polymers: Hoʻohana nui ʻia ʻo UV-327 i ka hana ʻana i nā plastics a me nā polymers e hoʻonui ai i ko lākou kūʻē ʻana i ka hoʻohaʻahaʻa ʻana o UV.Kōkua ia i ka pale ʻana i ka ʻeleʻele o ka kala, embrittlement, a me ka nalowale o nā waiwai mechanical i hoʻokumu ʻia e ka ʻike UV.
Nā Pepa a me nā Pena: Hoʻohui ʻia ʻo UV-327 i nā ʻili a me nā pena e pale aku i nā ʻili mai nā hopena ʻino o ka radiation UV.Kōkua ia i ka mālama ʻana i ke ʻano, ka nani, a me ka lōʻihi holoʻokoʻa o nā uhi a me nā pena i ʻike ʻia i ka lā.
Adhesives and Sealants: Hoʻohana ʻia ʻo UV-327 ma ke ʻano he mea hoʻohui i nā mea hoʻopili a me nā mea hoʻopaʻa e hoʻonui ai i ko lākou kūʻē ʻana i ka degradation UV.Kōkua ia i ka pale ʻana i ka melemele, nalowale o ka adhesion, a me ka hōʻemi ʻana i ka hana ma muli o ka ʻike ʻana i ke kukui UV.
Hoʻohana maʻamau ʻo UV-327 i ka hana ʻana i nā ʻāpana kaʻa a me ka aerospace e hoʻomaikaʻi ai i kā lākou pale UV.Kōkua ia i ka hoʻolōʻihi ʻana i ke ola a me ka mālama ʻana i ka nānā ʻana o kēia mau huahana.
Nā Fiber a me nā Textiles: Hoʻohui ʻia ʻo UV-327 i nā fibers a me nā textiles e hāʻawi i ka pale mai ka radiation UV.Kōkua ia i ka hōʻemi ʻana i ka mae ʻana o ka waihoʻoluʻu, ka hoʻohaʻahaʻa ʻana i ka lole, a me ka nalowale o ka ikaika ma muli o ka lōʻihi o ka ʻike ʻana i ka lā.
Nā huahana mālama pilikino: Hoʻohana ʻia ʻo UV-327 i nā hana pale lā e pale aku i ka ʻili mai nā hopena ʻino o ka radiation UV.Hana ia ma ke ʻano he absorber kūpono, e hōʻemi ana i ka hopena o ka lā a me ka pōʻino o ka ʻili.
