3,4,9,10-Perylenetetracarboxylic dianhydride,a supplier showing what it is really ！

issued by the good supplier,BST Tianjin Co., LTD,

First of all ，let us view the  Molecular structural formula that is interested in you maybe below

Besides ，its basic Chemical & Physical Properties is also important
Second ,what is its MSDS that can show you how to handle it when using it ?

MSDS

Whenever, safe is always in the first place,can you view the information below?

Safety Information

Third，Of course,the most important thing is what are the usages of 3,4,9,10-Perylenetetracarboxylic dianhydride,do you

want to know?

Important intermediate for synthesizing perylene dyes and pigments

This pigment variety, Perylene Tetramethylene Anhydride (PTCA), can provide highly transparent and non-transparent products, with a bright red color and a stronger yellow hue compared to Quinacridone. It is also suitable for color matching with organic or inorganic pigments (molybdenum chromium red). Mainly used in high-end industrial coatings and decorative coatings, such as automotive coatings and outdoor coatings, with a light fastness of 7-8 levels; The solvent resistance and gloss resistance of the paint are good, and due to its molecular structure, it is sensitive to alkali, with a heat resistance of 260 ℃; It is also used for coloring the raw slurry of polyacrylonitrile; More commonly, various important varieties of perylene red pigments are synthesized through ammonolysis reactions with different substituted aromatic amines or fatty amines.

if you have known other new usages,welcome tell you,we can disucss each other on such new fields.

Will you hope the standard specification of the chemical in general ?

The specification of 3,4,9,10-Perylenetetracarboxylic dianhydride is as follows
