Detailed Product Description
Non-toxic, Anticorrosive Pigment--Aluminum Tripolyphosphate
Sanjing Aluminum Tripolyphosphate series, non-toxic white anticorrosive pigments for paints,
are produced by Xinjing Science&Technology Co.Ltd.
The cooperation began the research of Aluminum Tripolyphosphate in 1982.
It was the first institution in China that has successfully developed and produced this product on the industrial scale.
The product series were classified as the national industrialization project.
The quality standards of the products was the same as it used by developed countries.
The qualities of products were tested by Changzhou Paint Res. Inst. of National Department of Chemical Industry, and Wuhan Paint Res. Inst. etc.
According to the standards of Volkswagen, Germany, the tests results showed that Sanjing products' performance of
anticorrosion was better than other toxic anticorrosive pigments such as lead red or zinc yellow.
