Zomatira zamagulu awiri ziyenera kugwiritsidwa ntchito ndi nthawi yoyenera mutayika RFE.
Kutalika kwa nthawi yogwira ntchito sikungokhudzana ndi zomatira za polima, komanso zigawo zina zofunikira (monga utomoni, Antioxygen, plasticizer, solvent, etc.
Pafupi ndi nthawi yoyenera, nthawi zambiri maola angapo kapena tsiku limodzi logwira ntchito, zomatira zimakhala zovuta kugwira ntchito, ndipo kukhuthala kumakwera posachedwa.
Pomaliza, imakhala yosasinthika odzola.Zomatira zamtundu wa 100, Hydroxyl polyurethane (mbiri ya Polyurethane pafupifupi 20%), RFE imachita 4-7.Chloroprene rabala (Rubber account pafupifupi 20%), RFE amachita 4-7.
