UV-123 ndi amphamvu amine kuwala stabilizer, ndi otsika zamchere, akhoza kuchepetsa zimene ndi asidi zigawo zikuluzikulu mu ❖ kuyanika dongosolo, makamaka abwino mu dongosolo munali zinthu zapadera monga asidi mankhwala ndi chotsalira chothandizira; imatha kuteteza bwino kutayika kwa kuwala, kusweka, kutuluka thovu, kugwa ndi kusinthika, motero kumapangitsa moyo wautumiki wa zokutira; gwiritsani ntchito ndi ultraviolet absorbent kuti mukwaniritse bwino ntchito yolimbana ndi nyengo.
Oyenera: zokutira zamagalimoto, zokutira zamafakitale, zokutira zokongoletsera ndi zokutira zamatabwa.
Onjezani kuchuluka: nthawi zambiri 0.5-2.0%. Mayesero oyenerera adzagwiritsidwa ntchito kuti adziwe kuchuluka koyenera kuwonjezeredwa pakugwiritsa ntchito.
