ʻO UV5151 kahi hui wai o kahi mea hoʻomoʻa UV 2-(2-hydroxyphenyl)-benzotriazole hydrophilic (UVA) a me kahi mea hoʻopaʻa kukui amine hindered kumu (HALS). Ua hoʻolālā ʻia e hoʻokō i nā koi kumukūʻai kiʻekiʻe/hana a me ke kūpaʻa o nā uhi ʻoihana a me nā mea hoʻonaninani i lawe ʻia e ka wai a me ka mea hoʻoheheʻe. ʻO ka absorbance UV ākea o ka UVA i hoʻohana ʻia e kūpono ia no nā ʻano uhi like ʻole no ka lāʻau, nā plastics a me ka metala. Hāʻawi ka hui synergistic i ka pale uhi maikaʻi loa e kūʻē i ka hōʻemi ʻana o ka gloss, ka haki ʻana, ka blistering, ka delamination a me ka hoʻololi kala a hāʻawi i ka pale substrate piha.
