Zviviri-zvikamu zvinonamira zvinofanirwa kushandiswa nenguva inoshanda mushure mekuisa muRFE.
Hurefu hwenguva inoshanda haina hukama chete neiyo polymer yemukati yekunamira, asiwo zvimwe zvakakosha zvikamu (senge resin, Antioxygen, plasticizer, solvent, nezvimwe.
Kana iri pedyo nenguva yakakodzera, kazhinji maawa mashomanana kana zuva rimwe rekushanda, kunamira kunowedzera kuoma kushanda, uye viscosity inokwira nokukurumidza.
Pakupedzisira, inova jelly isingachinjiki. 100 yemhando yekunamira, Hydroxyl polyurethane ( Polyurethane account inotenderedza 20%), RFE inoita 4-7. Chloroprene rubber (Rubber account yeanenge 20%), RFE inoita 4-7.
