Pono e hoʻohana ʻia ʻelua mea hoʻopili i loko o ka manawa kūpono ma hope o ka hoʻokomo ʻana i RE.ʻAʻole pili ka lōʻihi o ka manawa kūpono i ka ʻikepili polymer o ka adhesive, akā ʻo nā mea ʻē aʻe e pili ana (e like me resin, antioxygen, plasticizer, solvent, etc.
Ke kokoke i ka manawa kūpono, maʻamau he mau hola a i ʻole hoʻokahi lā hana, ʻoi aku ka paʻakikī o ka hoʻopili ʻana, a piʻi koke ka viscosity.ʻO ka hope, lilo ia i ka jelly hiki ʻole ke hoʻololi.100 mea hoʻopili maikaʻi, Hydroxyl polyurethane (Polyurethane account no kahi o 20%), RE dose 4-7.Chloroprene rubber (Rubber account for around 20%), RICHEST RE is 4-7.
