Mbiri ya chisinthiko ya akampaniyi

Kusintha kwa malonda a EPTV Magawo awa amatchedwa "epoxide", yomwe pamapeto pake idadziwika kuti epoxy pophatikiza ndi polylol kapena ester. Ngakhale mawonekedwe oyambawa anali ndi ntchito zambiri zothandiza, kugwiritsa ntchito kwake kunangokhalabe chifukwa chotsika mtengo komanso kusowa kwa zinthu zopezeka. Mu 1940s ofufuza angapo adagwiranso ntchito pokonzanso pazoyambirira za epoxy kuphatikiza ku America Richard Richard O Olrolexe Oxide ndi phenol novolak. Nthawi yomweyo asayansi aku Britain adayamba kuyesa kupanga mitundu yosiyanasiyana monga Amine ndi ma acid omwe amatha kugwiritsidwa ntchito posintha mawonekedwe monga kale komanso kutsatsa njira kuti ikhale yopanga zinthu zamakono zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga zinthu zopanga bwino. Pa nkhondo yachiwiri yapadziko lonse ya epoxies yowonjezereka ndikupanganso kufunidwa kwa ogulitsa zakuthupi kuti athe kuthana ndi kutentha, kugwiritsa ntchito mankhwala etc. Kukula kwa ukadaulo uwu kenako kudapitiliza m'ma 1950s komwe kumachitika mu ma referestem onse opanga ma rabartem ndi opangidwa ndi aslastomer 'kapena opukutira). Pofika kumayambiriro kwa 1960 Pamodzi ndi maluso ophatikizika okhudzana ndi tinthu tating'onoting'ono tofana ndi zida za diamondi zoperekera zopanga zina zowonjezera pazaka makumi awiri nthawi isanachitike nthawi imeneyi. Nthawi zonse izi zikuwonetsa kuti tabwera mpaka pano kuyambira koyamba.
