Brief Introduction
Pigment red 179 is a perylene pigment, which mainly refers to a class of perylene tetracarboxylic acid diimide compounds obtained by condensation of perylene tetracarboxylic acid or perylene tetracarboxylic anhydride with different amine compounds. Red to brown perylene pigments are a kind of high-performance organic pigments, which have extremely high resistance to organic solvents and thermal stability, excellent light fastness, weather fastness, color penetration resistance, migration fastness and other properties. They are widely used as high-grade industrial coatings such as automotive original topcoats and touch up paints, as well as high-grade plastic colorants of vinyl polymers, polyethylene, polypropylene, fiber plastics. Used for coloring industrial buildings, automotive coatings, printing inks, PVC plastics, etc.

Brief Introduction
Once widely used in cotton; For the dyeing of viscose, it is easy to change into blue in case of acid, and there is no appropriate treatment method to improve its wet treatment fastness. Therefore, since the advent of insoluble azo dye and direct acid resistant red 4BS, the use of this product in dyeing has decreased gradually, but it is used in papermaking industry. It can also be used as acid-base indicator, i.e. Congo red test paper, pH 0 (blue violet) - 0 (red). In addition, it is also used for biological staining and analytical reagents. It is used as an adsorption indicator for the determination of halide, thiocyanate and zinc. It is used as a chromogenic agent for the determination of thiophosphate herbicides by TLC. It is also used as a biological stain.
