Lapho izigqoko zivezwa ngaphandle, izici ezinjengomswakama, ukushisa nemisebe ye-UV zingabangela ukuba ziwohloke.Ngokuvamile, izakhi ezisengozini kakhulu ekugqokeni ama-resin akha ifilimu nama-powders.Imisebe ye-Ultraviolet namanzi kubangela ukuthi lezi zinto ziwohloke amakhemikhali, futhi lokhu kusabela kokuwohloka kuvame ukusheshisa lapho amazinga okushisa enyuka.Ukuwohloka kwezingubo ezibangelwa imisebe ye-ultraviolet kuvame ukubizwa ngokuthi i-photooxidation.Ukusabela kubangelwa imisebe ye-ultraviolet.Umoya-mpilo osemkhathini uhilelekile ekucekeleni phansi kwamakhemikhali.Izinto ezinjalo ezimunca i-photon zibizwa ngokuthi ama-chromophores futhi zingaba amaqembu okugcina ezinhlayiya ze-pigment, i-backbone noma i-polymer binder, ukungcola, izincibilikisi ezisele, noma izithasiselo.Lapho ama-photon esemuncwa, i-chromophore ikhipha amandla.Le nqubo ivame ukufezwa ngokuphula isibopho esihlangene ukuze kwakhiwe ama-radicals amabili mahhala.Lawa ma-radicals ngokuvamile asebenza kakhulu emoyeni futhi ahlangana nomoya-mpilo ukuze akhe ama-radicals mahhala agxile kumoya-mpilo.Uma sezisunguliwe, lawa ma-radicals anganqamula izibopho zamanye amakhemikhali e-organic ngokusebenzisa izinyathelo ezihlukahlukene zamakhemikhali, enze ukusabela kweketango okuholela ekonakaleni kwe-polymer.Ngokuya nge-polymer, ukwanda noma ukwehla kwe-cross-linking density, noma inombolo enkulu noma encane yama-molecule, ingabonwa.Owokuqala angase abangele ukuqhekeka kwe-coating;Lokhu kokugcina kungase kuholele ekukhoneni kwe-viscidity, ukumelana ne-solvent noma ukumelana nokunwaya.Futhi i-gloss kapende izolahleka, futhi umbala uzoshintsha.
Ngaphandle kwe-photooxidation, ifilimu eyenza i-resin ekugqokeni ingancishiswa yi-hydrolysis, ikakhulukazi lapho izinga lokushisa lokugqoka likhuphuka ngaphansi kokukhanya kwelanga.Ngaphansi kwalezi zimo, ama-molecule wamanzi amuncwa ku-coating angahlasela izibopho eziqinile ku-resin futhi ahlukanise amaketanga e-polymer, okuholela ekunciphiseni isisindo samangqamuzana.Ama-polyester nama-alkyd resins asengozini kakhulu kulo mphumela kunama-polyurethanes nama-epoxies.
