HP RED 23210 / PIGMENT RED 166

Pigment Red 166

P.R.166 affords clean yellowish shades of red. It is broad in scope and in this respect resembles the somewhat bluer disazo condensation pigment P.R.144. Its main area of application, however, is in plastics and in spin dyeing. In the plastics sector, P.R.166 is used primarily to color PVC and polyolefins. The pigment is almost completely fast to bleeding in plasticized PVC. Similarly colored pigments of other classes perform poorer in terms of migration and lightfastness and also regarding heat stability.
