I-anhydride ye-Maleic inezici zekhwalithi ezinzile nokusebenza okuhle kakhulu ekukhiqizweni kwe-resin. Idlala indima ebalulekile ekuhlanganisweni kwama-resin ahlukahlukene njengama-polyester resins, ama-alkyd resins, nama-phenolic resins aguquliwe. Ukusebenza okuhle kakhulu kwe-anhydride ye-maleic kanye nokuhambisana nezinhlobo ezahlukene zama-polymers kuthuthukisa izakhiwo zemishini nezishisayo ze-resin, iyenze ifanelekele uhla olubanzi lwezinhlelo zokusebenza.

Esinye sezici eziyinhloko ze-anhydride ye-maleic ukuncibilika kwayo emanzini, okungakha i-maleic acid lapho incibilika emanzini. Lesi sici senza kube lula ukuphatha nokuhlanganisa ezinhlelweni ezisekelwe emanzini, ngokuqhubekayo sandise ukusetshenziswa kwayo ekukhiqizeni ama-resin asekelwe emanzini. Ukwengeza, i-anhydride yesilisa ibonakala njengamakristalu amhlophe anobuningi obungu-1.484 g/cm3, ihlinzeka ngezinkomba zokuhlanzeka nekhwalithi yayo.
Ukuqinisekisa ukuphathwa okuphephile kwe-anhydride ye-maleic kubaluleke kakhulu. Kunconywa ukulandela imihlahlandlela yokuphepha ehlanganisa i-S22 (Ungaluphefumuli uthuli), i-S26 (Uma uthintana namehlo, hlambulula ngokushesha), S36/37/39 (Gqoka izingubo zokuzivikela ezifanele, amagilavu nokuvikela iso/ubuso) kanye ne-S45 ( Uma kwenzeka ingozi noma ukuphatheka kabi ngokomzimba, funa usizo lwezempilo ngokushesha). Uphawu C oluyingozi lubonisa ukuthi kungaba yingozi empilweni futhi kufanele kubhekwane nakho ngendlela efanele. Izitatimende ezinobungozi zifaka u-R22 (oyingozi uma ugwinyile), u-R34 (ubangela ukusha) kanye no-R42/43 (ungabangela ukuzwela ngokuhogela nokuthinta isikhumba).
I-anhydride ye-Maleic inekhwalithi ezinzile futhi isetshenziswa kabanzi ekukhiqizeni i-resin, futhi iyinhlanganisela ebalulekile embonini yamakhemikhali. Inikeza izinzuzo ezibalulekile ezifana nezakhiwo ezithuthukisiwe ze-resin kanye nokuvumela ukwakheka okusekelwe emanzini. Ukuguquguquka kwayo kanye nokusebenza kabusha kuyenza ilungele izinhlelo zokusebenza ezihlukene zezimboni nezentengiso, okuvumela ukudalwa kwekhwalithi ephezulu nemikhiqizo ehlala isikhathi eside.
Kafushane, i-anhydride ye-maleic, eyaziwa nangokuthi i-MA, iyinhlanganisela yezinto eziphilayo esetshenziswa kakhulu ekukhiqizeni i-resin. I-anhydride ye-Maleic, enekhwalithi yayo ezinzile, ukunyibilika kwamanzi, nokuhambisana okuhle kakhulu nama-polymers, ithuthukisa ukusebenza kwe-resin futhi iyenze ifanelekele ukusetshenziswa okuhlukahlukene. Kodwa-ke, ngenxa yezingozi zezempilo ezingaba khona ze-anhydride ye-maleic, ukuphatha i-anhydride ye-maleic kudinga ukubambelela ngokuqinile eziqondisweni zokuphepha. Sekukonke, i-anhydride ye-maleic idlala indima ebalulekile embonini yamakhemikhali futhi ibalulekile ekwenzeni ama-resin asebenza kahle kakhulu.
