High-opacity inorganic yellow pigment (cadmium sulfide) for industrial paints, coatings, printing inks and engineering plastics.
Cadmium Yellow The chemical composition of pure cadmium is cadmium sulfide or cadmium sulfide and zinc sulfide solid solution. Cadmium yellow color bright and full (saturation of up to 80% to 90%), the chromatographic range from yellow, yellow by yellow to yellow.
Note on naming: Cadmium Yellow is commonly listed as Pigment Yellow 37 (PY37) in the Color Index/Chemical catalogues — we highlight this alias so purchasing and compliance teams can cross-reference technical specifications easily.

Cadmium compounds are regulated in many jurisdictions and classified as hazardous. Our product is supplied with full safety data sheets (SDS) and recommended handling instructions. Customers must ensure compliance with local laws (REACH, RoHS, local environmental & workplace rules) before use. For low-risk or non-cadmium alternatives, please contact us for matched color formulations.
Note:The data contained here are based on our current knowledge and experience. It is the responsibility of user to test our products before the final application.
Cadmium Yellow (PY37) is an inorganic cadmium sulfide pigment that offers superior opacity, stronger tinting strength and better heat resistance than many organic yellows. In real-world coatings and plastics where hiding power and long-term color stability are critical (e.g. exterior finishes, high-temperature processing), PY37 often outperforms organic alternatives despite its regulated status. That said, selection should balance performance benefits with regulatory and end-use constraints.
Pigment yellow 37 (PY37) is broadly compatible with most common binders — acrylics, alkyds, epoxies and many thermoplastics — but dispersion characteristics and optimum pigment volume concentration (PVC) vary by system. For waterborne systems, ensure proper wetting agents and dispersants are used; for plastisol/extrusion processes, consider grade and surface treatment. We provide technical trials and dispersion guidance specific to your binder on request.
We supply a complete technical pack (SDS, compliance declarations and test reports) with each shipment. Because cadmium use is restricted in some markets, we also provide substitution guidance and matched non-cadmium options when required. Please tell us your target market and application so we can supply the correct regulatory documentation and advise on safe disposal and workplace controls.
