Description
1. Chemical Properties and Classification
Vat Orange 7 is also known as Pigment Orange 43, or C.I. 71105 is a high performance organic pigment that belongs to the anthraquinone-reducing dye family. The molecular formulation is C 26H 12 N 4O 2, with a weight of about 412.41, and a CAS code of 4424-06-0.
In terms of chemical structure, the compound has a complex fused ring skeleton of dibenzimidazole phenanthroline diketone and belongs to the perylene derivative. This large conjugated system endows it with bright color light and excellent chemical stability.
2. Physical characteristics and morphology
At room temperature, Vat Orange 7 is a fine orange to brown powder. Its density is about 1.66 g/cm ³, melting point is about 170 ° C, and the maximum absorption wavelength in DMSO is 480 nm. This pigment has excellent light resistance and weather resistance, as well as excellent heat resistance and migration resistance. It has high coloring strength, but may have a slight tendency to darken when exposed to outdoor environments in solid color applications.
3. Industry positioning and production background
Vat Orange 7 belongs to high-end organic pigments, and its production involves complex closed-loop condensation reactions, with a high technical threshold. China released the group standard “Restoring Brilliant Orange GR (C.I. Vat Orange 7)” in 2021, providing a standardized basis for its quality control. As one of the few orange varieties that can meet both “high color fastness” and “vividness” requirements, this product holds an irreplaceable position in high-end applications that require long-term outdoor exposure.

The application of Vat Orange 7
The main use of Vat Orange 7
Vat Orange 7, as a high-end anthraquinone organic pigment, plays a core role in various industrial fields with strict requirements for product durability due to its excellent light and weather resistance, bright color light, and excellent chemical stability.
High end Coatings and Automotive Industry
In the field of coatings, Vat Orange 7 is an important coloring agent that meets extreme outdoor durability requirements, especially suitable for high-performance industrial coatings.
Firstly, in terms of automotive coatings, it is used as the original paint and repair paint for luxury cars and buses, ensuring that the body coating maintains a bright and new orange or red color for many years under long-term UV exposure and acid rain erosion.
Secondly, in architectural and industrial coatings, it is added to outdoor steel structure coatings that require long-term color fidelity, such as high-rise building exterior walls, bridges, storage tanks, and construction machinery.
In addition, it is also suitable for coil coatings and powder coating systems, and its excellent heat stability ensures the accuracy of color during processing.
Plastics and Special Materials Industry
Vat Orange 7 is an indispensable high-performance coloring agent in polymer systems that require high-temperature processing or long-term outdoor use.
It is suitable for coloring materials such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and engineering plastics such as nylon (PA), polycarbonate (PC), etc. It can maintain stability at injection molding or extrusion temperatures up to 300 ° C without decomposition or color change.
This feature makes it widely used in automotive interior and exterior parts (such as instrument panels, bumpers), outdoor furniture, lawn mowing equipment casings, and electronic and electrical products, ensuring long-term color stability of the products.
Packaging and Special Printing Ink
In the ink industry, Vat Orange 7 is mainly used in high-end printing scenarios with special durability requirements, such as food packaging, metal decoration printing, and anti-counterfeiting printing of valuable securities (such as banknotes and stocks). Its bright color tone and excellent migration resistance ensure that the ink layer can maintain good visual effects even when stored for a long time or in contact with chemicals.
The use of Vat Orange 7 deeply reflects the core value of high-performance organic pigments in high-end manufacturing. It is not only a “color guard” that protects car and building coatings from fading, but also a “molecular stabilizer” that ensures outdoor plastic products do not fade. At the same time, it plays an important anti-counterfeiting role in the field of special printing.

FAQ
The fabric is ideal for outdoor applications and high-end textiles. It has excellent lightfastness (7-8), high heat resistance and excellent chlorine/washfastness.
It is insoluble in water. Reduced in alkaline sodium sulfite, it becomes soluble leucobody, which can be adsorbed on fibers. Then, the dye is oxidized to become insoluble for permanent fixation.
Primarily suitable for cellulose (cotton/viscose). Also suitable for nylon, vinylon, polyester/cotton blends and other carrier systems.
We offer a 100g free sample; we also provide COAs, MSDSs, TDSs, and SGS certificates for customs clearance and compliance.
