Pigment Red 170, Red F5RK, Red F3RK
Briefing
Pigment Red 170 is a very strong and brilliant bluish red pigment with good lightfastness and high transparency. Application of pigment red 170 is fiber and polyolefins.
There are two grade P.R.170, one is F3RK and the other is F5RK. Both are halogen-free, F3RK is high hiding power yellowish and F5RK is transparent bluish.
F3RK could use in PVC while could bloom in flexible PVC, more solvent resistance, mostly used in coating, could blend with quinacridone and molybdate orange. F5RK could not be used in PVC.
