Ana iya amfani da DNNSA a matsayin mai kara kuzari ga shafa fenti, kuma ana iya amfani da shi azaman babban kayan aiki don samar da masu kara kuzari ga fenti na yin burodi na amino. Maganin Dinonylnaphthalenesulfonic acid ya dace da tsarin fenti na anodic electrophoretic saboda rashin kyawunsa. A cikin tsarin electrocoat na anodic, maganin dinonylnaphthalenesulfonic acid yana canja wurin da kuma adanawa cikin sauri, kuma yana haɓaka amsawar warkarwa na ƙungiyoyin hydroxyl, carboxyl da amino functional tare da alkylated amino resins. Hakanan ya dace da tsarin solvent da na ruwa don inganta juriyar tsatsa. Saboda yawan wutar lantarki mai tsauri. Saboda haka, DNNSA ya dace musamman don fesawa na electrostatic. Ana amfani da Dinylnaphthalenesulfonic acid DNNSA don ƙarfe mai coil, fenti na gwangwani, fenti na mota, saman masana'antu gabaɗaya da primer. Adadin ƙari shine 0.5--2%, dinonylnaphthalenesulfonic acid na iya rage zafin yin burodi da rage lokacin yin burodi. Lokacin yin burodi, inganta tauri da juriyar sinadarai na fim ɗin fenti.
