Product Description Product Name Hermcol® Light Chrome Yellow (Pigment Yellow 34) C.I. No  Pigment Yellow 34 CAS No  1344-37-2 EINECS No.  215-693-7 Molecular Formula  PbCrO4 Pigment Class  Chrome Yellow Features Chrome Yellow is a natural yellow pigment made of lead(II) chromate (PbCrO4). It was first extracted from the mineral crocoite by the French chemist Louis Vauquelin in 1797. Because the pigment tends to oxidize and darken on exposure to air over time, and it contains lead, a toxic, heavy metal, it has been largely replaced by another pigment, Cadmium Yellow (mixed with enough Cadmium Orange to produce a color equivalent to chrome yellow). Cadmium pigments on their own are toxic as well from the cadmium content, and have themselves been replaced with azo pigments. This pigment has bright color, with strong tinting strength, high hiding power, good light fastness and dispersibility. Application Paints and coatings, industrial paints, coil coatings, marine coatings, aviation coatings, automotive OEM and re-finish paints, architectural coatings, construction machinery coatings, shipping container coatings, fluorocarbon coatings, heat-resistant coatings, plastics, functional master batches, artificial leather.
