Shaoyang Zhongcai Manufacturing Co., Ltd., formerly known as Shaoyang Xiangzhicai Chemical Co., Ltd., is a medium-sized production base for fine chemical products in the central and southern regions. It has its own workshop to produce medium chrome yellow, deep chrome yellow, light chrome yellow, lemon yellow, and orange chrome yellow products. The products are strictly produced in accordance with GB/T3184-1993 standards.
High tech Zhongcai brand coated lead chrome yellow is a series of yellow inorganic pigments obtained by deep precipitation of coating materials such as dichromate, sulfate, soluble lead salt, silicon series and antimony series. The main components are lead chromate and lead sulfate, as well as dense silicon and antimony coating materials. By adjusting the ratio of lead chromate and lead sulfate, various chromatographic varieties from lemon to orange can be obtained. By adjusting the ratio and thickness of silicon coated antimony coating, lead chrome yellow varieties with different temperature and weather resistance can be obtained. The product has bright colors, strong covering power, high coloring power, solvent resistance, heat resistance, sun resistance, environmental protection, and easy grinding and dispersion. Can be mixed with organic pigments for application.
The molecular formula of the chrome yellow coating in the high-tech Zhongcai brand coating is PbCrO4+xAl (OH) 3, and the coating material is silicon and antimony, widely used in industries such as paint, coatings, rubber, and plastics.
