Features

  • Almost no fogging problem in automotive applications
  • Low foaming properties → suitable for jet dye
  • Good shelf stability
  • Very fine particle size → suitable for piece dyeing as well as package dyeing
  • Stable at very high temperature → no generation of thermal migration problems when used in continuous disperse dye pad/thermosol or printing applications
