Lead-free Molybdate Red C6630 is an environmentally improved molybdate red pigment designed as an alternative to conventional Pb-containing molybdate pigments.
It provides a clean red shade with superior thermal resistance, excellent light fastness and good chemical resistance, while significantly reducing lead-related environmental and handling risks.
Compared with traditional PR104 grades, C6630 delivers safer formulation flexibility, lower conductivity, and stable tinting performance in both solvent-based and water-based coating systems.

Yes — our Lead-free Molybdate Red is produced without intentionally added lead. We provide Safety Data Sheets (SDS), Technical Data Sheets (TDS) and third-party test reports on request. If you need confirmation for a specific regulation (RoHS, REACH, etc.), tell us which one and we’ll supply the relevant test documentation.
Expect a bright about Lead-free Molybdate Red, vivid red with high tinting strength and consistent shade across batches. The pigment shows good lightfastness and thermal stability for typical coatings, inks and plastics processes. We stock grades optimized for high-temperature polymer processing and for formulations requiring extra UV/chemical resistance — request the TDS for exact metrics (ASTM lightfastness, recommended dispersion percentages, recommended processing temperatures).
Lead-free Molybdate Red Suitable for coatings (architectural/industrial), printing inks, plastics (masterbatches, injection, extrusion), rubber and latex systems. For best results: pre-disperse according to your system (let us know solvent vs waterborne vs melt), start with manufacturer-recommended loading levels in the TDS, and test small batches for migration or compatibility in your final formulation. We can provide sample packs and recommended dispersion recipes for your specific application.
