Name: Lemon yellow-501
Appearance: yellow powder
HS Code: 32062000
CAS NO: 6054-97-3
Molecular formula: PbCrO4
Packing: 25kg lining compound bag
Characters:
1. It has good heat, acid and alkalis resistance, and light fastness, easily dispersed.
2. It is prepared by the precipitation of chromate salt with lead nitrate solutions with special surface treatment of silica, aluminum and other additives. The pigment particles of the treated chrome yellow are coated with a layer of encapsulated protective coating, so the pigment properties are greatly improved, and it is suitable for many industrial applications.
3. It has a clean bright color, with outstanding weather resistance and light fastness. The product can withstand over 200 C. Deg, under such temperature the color would not change. The coated pigment can easily dispersed in paint, printing ink, rubber and plastics media, with good chemical resistance. As compared with ordinary chrome yellow, it contents less soluble lead and conformed too many safety regulations, reduces the environmental hazard. It can be used in heat fusion road paint, which have special demand on weather, chemical resistance and light fastness.
