Gin ma gengo dongo pa hydroxypropyl acrylate ki acrylic acid, pi tic gi maber, pe twero gengo yubu ki keto pa calcium carbonate ki calcium phosphate keken ento bene gengo dongo pa zinc salt ki poko iron oxide. I kare ni, gi tye ka tic kwede i yubu pii. Ki dongo pa diro me yubu pii ki yenyo ki dongo jami manyen ma pat pat me yubu pii, diro me yubu pii ma ki lwongo ni fluorescent tracing dong ki tiyo kwede. Yo mayot me nongo jami ma ryeny ma ki lwongo ni fluorescent polymers tye ki i copolymerization pa acrylic acid, hydroxypropyl acrylate polymers, ki fluorescent monomers.
