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 across demanding industrial applications. Its exceptional heat stability and lightfastness make it a benchmark colorant where organic alternatives cannot meet performance thresholds. In plastics and polymers, it withstands high processing temperatures.

Engineering resins such as polyolefins and PVC utilize this pigment without color shift or degradation. Industrial coatings manufacturers use it to achieve durable, high-opacity finishes on heavy machinery. It is also ideal for agricultural equipment and road-marking paints where long-term exterior exposure is a requirement. In printing inks for packaging, it provides consistent hue strength and resistance to bleed.

Rubber compounders and sealant formulators incorporate it where pigment stability under mechanical stress is a priority. It is also favored in environments where chemical exposure is a procurement concern. Lead sulfochromate yellow is supplied as a dry powder, typically in fine-milled grades optimized for dispersion. It works effectively in solvent-borne, water-borne, and various resin systems.

The material is available in Technical-grade, with particle size distribution and oil absorption values specified to suit coatings. These specifications ensure compatibility with modern plastics processing. Supply is subject to regulatory controls in multiple jurisdictions. Buyers should confirm all necessary compliance documentation and safety data sheets prior to final procurement for industrial use.
