Iyo impuzu zihuye hanze, ibintu nkubushuhe, ubushyuhe hamwe nimirasire ya UV birashobora kubatera kwangirika.Muri rusange, ibice byoroshye cyane mubipfundikizo ni firime ikora ibisigazwa nifu.Imirasire ya Ultraviolet n'amazi bitera ibyo bikoresho kwangirika kwimiti, kandi ibyo bitesha agaciro bikunda kwihuta mugihe ubushyuhe buzamutse.Kwangirika kwimyenda iterwa nimirasire ya ultraviolet bakunze kwita fotooxidation.Igisubizo gikururwa nimirasire ya ultraviolet.Oxygene mu kirere igira uruhare mu kwangiza imiti.Ibintu nkibi bikurura fotone byitwa chromofores kandi birashobora kuba amatsinda yanyuma yibice bigize pigment, umugongo cyangwa imigozi ya polymer, umwanda, ibishishwa bisigaye, cyangwa inyongeramusaruro.Fotone imaze kwinjizwa, chromofore isohora ingufu.Ubu buryo busanzwe bugerwaho mugucamo covalent guhuza ibice bibiri byubusa.Izi radicals zisanzwe zifata cyane ogisijeni kandi igahuza na ogisijeni kugirango ikore radicals yubusa.Iyo radicals imaze gushingwa, irashobora guca imvano yindi miti kama ikoresheje intambwe zitandukanye za chimique, bigatera urunigi rutera kwangirika kwa polymer.Ukurikije polymer, kwiyongera cyangwa kugabanuka mubucucike bwambukiranya, cyangwa umubare munini cyangwa muto wa molekile, birashobora kugaragara.Iyambere irashobora gutera igifuniko;Iheruka irashobora kuganisha ku gufunga ibishishwa, kwihanganira ibishishwa cyangwa kwihanganira.Kandi gloss irangi izabura, kandi ibara rizahinduka.
Usibye gufotora, firime ikora resin muri coating irashobora guteshwa agaciro na hydrolysis, cyane cyane iyo ubushyuhe bwa coating bwiyongereye munsi yizuba ryinshi.Muri ibi bihe, molekile zamazi zashizwemo mugutwikiriye zirashobora gutera imigozi ya covalent muri resin hanyuma igaca iminyururu ya polymer, bikavamo uburemere buke bwa molekile.Ibisigarira bya polyester na alkyd birashobora kwibasirwa niyi ngaruka kuruta polyurethanes na epoxies.
