Sudaperm™ Red 2963KF is an advanced performance pigment containing pigment red 170 or naphthol (CAS No. 2786-76-7). It provides a yellowish-shade red color, with high color strength and excellent lightfastness. This pigment also has a controlled low filter pressure value to meet the stringent requirements of masterbatch industries for film and fiber applications, such as polyolefin films, PP fiber, and EVA.
Sudaperm™ Red 2963KF has limitations in p-PVC applications due to its tendency to migrate in resin.
