1964, Coran et ŵanthu kuyana na ivyo vikasangika pa kusanda kwa Vulcanizate, nthowa ya vulcanization ya 2-}mercapto-thizole (MBT) Mchere wa Zinc ukapangika: Mchere wa Thiazole zinc uwo ukachitika na molekyulu ya sulfure, wakapanga MS-SX-SM, MS-SX-SM na raba hydrocarbon persond, ndipo wakapanga vigaŵa vyapakati vyakugwira ntchito . Kugwira ntchito ni mtundu wa sulfide wambura kugaŵikana, na gulu la kukhozgera vulcanizing kuumaliro, ndipo para likuvunda pachokopachoko kuti lipangire vigaŵa vyaulele, vigaŵa vyakufwatuka vyakuchitika vikuchitika na raba hydrocarbons kuti ŵasange labala wakupangika na zuwa.
Mu 1969, Manik na ŵanthu ŵanyake ŵakuthemba pa kuŵika mafuta gha asidi pa nkhongono ya Thiazole promoter, wakaŵika panthazi nthowa yakupambanapambana yakukwezgera {{ {{{ 1}} Wakagomezganga kuti thiazole-nga ni vulcanizing accelerator na mafuta ghakupangika na asidi wakupangika na mafuta gha ionic pa nyengo ya vulcanization, m'malo mwa radicals yaulere nga umo Coran wakayowoyera . Chakwamba, stearic acid wakuchita na ZnO kuti wapange zirc stearate. Pamanyuma, vyakuchitika vya zinc starate na mchere wa thiazole, na kukolerana kwa ma atomu gha O mu ma atomu na zinc steatete mu mchere wa thiazole zinc mchere, kuti paŵe mtundu wa Zn-s, kupanga mtundu wa kusintha (a), na (a) kuchita na molecule ya sulfure (B). ({{nthed) (B) kuzgora na hydrocarcarn wa labala kuti wapange MSSXR . MSSXR njambura kukhazikika, ma ayoni ghawemi na ghaheni ghakuvunda, ndipo ma ayoni ghakusazgana na hydrocarbon ya labala kuti ghapange labala wakupangika na vulcanized. .
