| Overview | 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 acid anhydride with different amine compounds. Red to brown perylene pigments are a type of high-performance organic pigments with extremely high organic solvent resistance and thermal stability, excellent light fastness, weather fastness, color permeability and migration fastness, etc. It is widely used as high-end industrial coatings such as automotive original topcoats and repair paints, as well as high-end plastic colorants for vinyl polymers, polyethylene, polypropylene, and fiber plastics. |
| Use | Used for coloring industrial buildings, automotive coatings, printing inks, polyvinyl chloride plastics, etc. |
| production method | method 1: melt N-methyl -1, 8-naphthalimide with potassium hydroxide.. Method 2: Methylation of 3,4,9,10-perylene tetramethyldiimide (C.I.Pigment Brown 26, 71129).. |
