Bayani: J425G wani lantarki ne mai rufin sinadari mai yawan cellulose sodium wanda aka lulluɓe shi da sinadarin sodium. Yi amfani da DCEP (mai nuna wutar lantarki kai tsaye), wanda ya dace da walda mai kusurwar ƙasa ta dukkan matsayi na dinkin zagaye a wurin bututun. Lokacin walda ƙasan Layer, ana iya walda shi a gefe ɗaya kuma a samar da shi a ɓangarorin biyu, kuma saurin walda yana da sauri.
Aikace-aikace: Ana amfani da shi don walda na kewaye na bututun ƙarfe na carbon daban-daban.
