Stannous pyrophosphate Description
Application: Mainly used for cyanide-free electroplating tin plating, as a filler in toothpaste, where it undergoes slight dissociation in toothpaste, contributing to dental health. In the dyeing and printing industry, it is used for coloring. In the ceramic industry, it is used for refining clay. In the paint industry, adding it appropriately can alleviate the settling rate of paint fillers in paint and improve paint performance.
Characteristics: At room temperature, it is a colorless or white powder, insoluble in water, and exhibits stable performance during use.
