Pigment Green 50(Cobalt Green) is a mixed metal oxide pigment of inverse spinel pattern. Compared to other green pingments, it has excellent heat resistance, light-fastness, acid resistance, alkali resistance and non-toxic, so it can be used in the area which required superior durability, especially in the area of color retention, gloss retention, chalk resistance, needs to use the pigment.
It can be use for fluorocarbon coatings, heat resistant coatings, plastics, ceramics, grass and artists' colors.

Yes — PG50 is formulated for high-heat processing and retains shade and tint strength under short to moderate thermal exposure. Always request the supplier’s heat-ageing/TGA data and run a pilot at your exact temperature profile before full production.
Use a pre-dispersed masterbatch with a matched carrier resin, minimize residence time at peak temperature, and control shear/oxygen exposure. If shade changes occur, run a short heat-ageing test and adjust carrier or stabilizers.
Start trials at low loadings (typically 0.2–1.0% pigment on polymer weight), use a twin-screw extruder for uniform distribution, and match carrier resin to the host polymer to prevent blooming or migration.
Perform a short extrusion or bake cycle on sample parts, then measure ΔE (color), gloss and perform a visual bleed/migration check. Compare to supplier TDS; if needed, request accelerated Xenon or QUV data for outdoor fade predictions.
