Pigment Red 254, Irgazin Red K 3840
Briefing
Pigment Red 254 is a semi-opaque mid shade red, an industry standard for all indoor.Recommended for polyolefin, comparable with Ciba Irgazin Red K 3840.
C.I.Pigment Red 254 shows high tinctorial strength, bleeding fastness, and high solvent resistance.
P.R.254 shows good hiding power, it is used primarily in automotive finishes wherever lead-free formulations are required.
For economical reasons, P.R.254 is frequently used in combination with the somewhat bluer but less weather fast opaque type of P.R.170.
