Zomatira zamagulu awiri ziyenera kugwiritsidwa ntchito mkati mwa nthawi yomwe ingagwiritsidwe ntchito mutayika RE.
Kutalika kwa nthawi yogwira ntchito sikungokhudzana ndi zomatira za polima, komanso zigawo zina zofunikira (monga utomoni, antioxygen, plasticizer, solvent, etc.
Ikayandikira nthawi yoyenera, nthawi zambiri maola angapo kapena tsiku limodzi logwira ntchito, zomatira zimakhala zovuta kugwira ntchito, ndipo kukhuthala kumakwera posachedwa.
Pomaliza, Imakhala yosasinthika odzola.100 zomatira zabwino, Hydroxyl polyurethane (Polyurethane account pafupifupi 20%), RE mlingo 4-7.Chloroprene rabara (Rubber account pafupifupi 20%), RE amachita 4-7.
