Dukansu farin rosin ruwa da rosin hydrogenated an gyaggyara rosin rosin na halitta.
Rosin ba fili guda ba ne, amma cakuda sinadaran:
Rosin ya ƙunshi kusan kashi 80% na rosin anhydride da rosin acid, kusan kashi 5 zuwa 6% na resin hydrocarbon, kusan kashi 0.5% na mai da kuma abubuwan daci.
Hydrogenated rosin:
Tun da rosin yana da sauƙi don crystallize, kuma resin hydrocarbon a cikin tsarinsa na kwayoyin ya ƙunshi nau'i biyu na haɗin gwiwa, yana da babban aiki, rashin kwanciyar hankali da sauƙi. Don inganta juriya na iskar shaka, ana iya shirya rosin hydrogenated ta hanyar amsa rosin tare da hydrogen a ƙarƙashin yanayin da aka lalata matsi.
Ruwa fari rosin:
Ruwa-fararen rosin rosin polyol ne mai launi mai haske. An yi shi daga rosin mai ladabi a matsayin ainihin albarkatun kasa ta hanyar hydrogenation, esterification da ƙarfafawa. Yana da abũbuwan amfãni daga ruwa fari, mai kyau tsufa juriya da kuma mai kyau dacewa da polymer kayan, wanda zai iya saduwa da musamman bukatun na m masana'antu.
Ana iya ganin cewa shirye-shiryen ruwan farin rosin yana buƙatar shiga ta mataki na hydrogenation rosin, amma ba'a iyakance ga mataki na hydrogenation ba, yana da kyakkyawan samfurin da aka gyara.
