Melamine waa la isku ururin karaa oo polymerized formaldehyde si loo soo saaro resin melamine, kaas oo loo isticmaali karo warshadaha balaastigga iyo daahan, iyo sidoo kale ka hortagga laalaabida iyo wakiilka daawaynta yaraynta ee dharka. Resinka la beddelay waxa loo isticmaali karaa dahaadh bir ah oo leh midab dhalaalaya, adkaysi, iyo adayg wanaagsan. Waxa kale oo loo isticmaali karaa xaashiyaha qurxinta ee adag, kulaylka u adkaysta, xaashida qoyaanka iyo maqaar cawlan, koolada loogu talagalay laminatesyada dab-demiska ee synthetic, wakiilada hagaajinta ama qallajiyeyaasha wakiilada biyuhu, iwm.
Caadi ahaan waxaa lagu buuxiyaa 25kg/durbaan, sidoo kale waxaa la samayn karaa xirmo habaysan.
