Phenothiazine ndeyepakati pemakemikari akanaka akadai semishonga uye dhayi. Icho chinowedzera chekugadzira zvinhu (inhibitor yekugadzirwa kweVinylon), mushonga wezvipembenene wemiti yemichero uye demintic yemhuka. Inobatsira zvikuru pa stomatostoma vulgaris, nodoworm, stomatostoma, nematostoma Shari uye nematostoma mitsipa yakanaka yemakwai.
Inonyanya kushandiswa seyakajeka inhibitor ye acrylic acid, acrylic ester, methacrylic acid uye ester monomer.
Anonzi Thiodiphenylamine. Inonyanya kushandiswa se inhibitor ye acrylic acid kugadzirwa. Inoshandiswawo mukugadzirwa kwemishonga uye dhayi, pamwe chete neanobatsira ekugadzira zvinhu (senge inhibitor yevinyl acetate girisi, iyo mbishi yerubha antioxidant). Inoshandiswawo semushonga wekuuraya zvipfuyo, mushonga wezvipembenene wemiti yemichero.
Ichi chigadzirwa chinoshandiswa zvakanyanya mukugadzira acrylic acid, acrylic ester, methacrylate uye vinyl acetate seyakanakisa inhibitor yealkenyl monomer.
