Pigment Yellow 139
Pigment Yellow 139 is a reddish shade pigment yellow powder. It has both opaque and semi-opaque type. The opaque type is more reddish than semi-opaque type. The increase of using amount will not affect its gloss. Pigment yellow 139 can be used together with inorganic pigment to replace chrome yellow. It is suitable in the high end coating like car finish paint, and it has a light fastness of 7-8 in alkyed melamine resin. It has a heat resistance of 250℃ in HDPE, but has color penetration problem in soft PVC. It is more suitable for low temperature plastics.

Feature
Pigment Yellow 139 has high coloring strength and is suitable for the coloring of high end products. Its heat resistance is good with 260℃/10min. Its light fastness can reach 6-7. Its maximum heat resistance is around 260℃, but its heat stability is not so well in plastics. So it is more suitbale for PVC and low density PE. In high temperature requirementplastics,such as PET,PMMA,PC,PA, PY139 may change in color. Its acid fastness and migration resistance is also excellent.
Application
Metal decorative ink,UV curing ink(offset and flexo),NC ink, Silk screen ink;Solvent based industrial coating, Powder coatings, automotive refinish;PE,PP,PVC
