Aplikasi:

Disaranake kanggo cat otomotif, cat industri, lapisan wesi, pasta percetakan, PVC, karet, PS, PP, PE, PU, inks adhedhasar banyu, inter pelarut, inks UV
Disaranake kanggo arsitektur lapisan, lapisan coil, inks offset.

Red pigmen 242 nduwe fase abang utawa kuning utawa fase abang sing gedhe, lan tahan ing pelarut lan resistensi asam / basa. Digunakake utamane kanggo pewarna plastik kayata PVC, PS, ABS, lan polyolefins. Kondhasi tahan panas nganti 300 ° C (1 / 3SD) ing HDPE, nanging kena pengaruh ubah bentuk dimensi. Iki cocog kanggo pewarnaan polipropilena mentah lan tahan kanggo migrasi ing PVC alus. Duwe kekuatan medium tinting; uga disaranake kanggo lapisan, lapisan otomotif, cat anti-glazing, lan tahan panas 180 ° C; kanggo inks percetakan kanthi dhuwur, kayata film PVC lan inks percetakan hiasan logam, film plastik berlamina, lsp.
