What is Lead sulfochromate yellow?
Lead sulfochromate yellow (CAS 1344-37-2), commercially known as Pigment Yellow 34, is a high-performance inorganic pigment delivering intense, opaque yellow coloration.
Where is Lead sulfochromate yellow used?
- Plastics and polymers: withstands high processing temperatures
- Engineering resins such as polyolefins and PVC: no color shift or degradation
- Industrial coatings: durable, high-opacity finishes on heavy machinery
- Agricultural equipment and road-marking paints: long-term exterior exposure
- Printing inks for packaging: consistent hue strength and resistance to bleed
- Rubber compounds and sealants: pigment stability under mechanical stress
- It works effectively in solvent-borne, water-borne, and various resin systems.
Good to know: Supply is subject to regulatory controls in multiple jurisdictions; buyers should confirm compliance documentation and safety data sheets before procurement.
Commercial specifications
- Particle size distribution and oil absorption values specified for coatings
