PIGMENT RED 176 – Introduction and Application
C.I. Pigment RED 176
Structure No. 12515.
Molecular formula: C32H24N6O5.
CAS number: [12225-06-8]
Color characterization
Bluish red,acceptable color saturation,bluer than Pigment Red 185,high tinting strength,need 0.53% pigment to prepare 1/3 SD of PVC with 5% titanium dioxide. The reduction is beautiful pink.
Pigment red 176 has bright color, good coloring strength, suitable for high-grade plastic ink, solvent ink, coating, plastic products, EVA foaming rubber, powder coating, strong master batch, soft plastic coloring. Light resistance is 6 grade.The thermal stability is above 300℃.Organic solvent resistance up to 4 ~ 5 level, no migration phenomenon.Mainly used for plastic coloring.Mainly used for coloring ink, paint, plastic products, used for car original paint and repair paint, plastic, ink, rubber and so on.
