CAS No. 15793-73-4 Pigment Permanent Orange Rl¹

Product Description Product Description Basic InformationCAS No.: 15793-73-4C.I. Number: 21115Molecular Formula: C34H28CI2N8O2Chemical Category: Organic pigment, azo pigmentPhysical PropertiesAppearance: Orange powderRelative Density: 1.40 - 1.60Specific Surface Area: 15 - 45 m2/gBulk Volume: 4.8 - 5.2 l/kgAverage Particle Size: 150 - 250 nmOil Absorption: 30 - 60 g/100gpH Value: 6.0 - 7.0Chemical PropertiesStability: Stable under normal temperature and pressure. It has good resistance to acids, alkalis, ethanol, esters, ketones, toluene, etc. Generally, the resistance grades to acids, alkalis, ethanol, esters, ketones and toluene are all around Grade 4.Fastness PropertiesLight Fastness: Grade 6 - 7 for full shade, and Grade 6 for tinted shade.Heat Resistance: The heat stability (10 minutes at full shade) is 200oC.ApplicationsInks: Can be used in various printing inks, but it is often replaced by Pigment Orange 5, as Pigment Orange 5 has more advantages in price and better light fastness.Plastics: Used in plasticized PVC. Although it has a certain tendency to bloom, its light fastness is much better than that of Pigment Orange 13. It can also be used in vinyl floor coverings and PVC cables.Coatings: Applicable to air - drying coatings, and can be used as a substitute for molybdate orange in industrial coatings.Key Terminology NotesAzo pigment: A type of organic pigment containing azo groups (?N=N?) in its molecular structure, which is widely used in inks, plastics and coatings due to its bright color and relatively low cost.Full shade / Tinted shade: In the field of pigments, "full shade" refers to the color state when the pigment is used at its maximum recommended dosage (without adding white pigments or diluents); "tinted shade" refers to the color state when the pigment is mixed with white pigments (such as titanium dioxide) or diluents to reduce the color concentration.Bloom tendency: A common problem in plastic coloring, which means that the pigment or additive migrates to the surface of the plastic product over time, forming a visible layer on the surface and affecting the appearance and performance of the product.Molybdate orange: An inorganic orange pigment with the main component of lead molybdate - chrome orange, which has good covering power but potential environmental risks (containing lead and chromium), so organic pigments like Pigment Orange 34 are gradually used as substitutes.Specification  Parameter nameUnitFigureWeather fastness/3Light fastness/5Heat resistanceoC160Overpainting resistance/4-5Water resistance/4Acid resistance/5Alkali resistance/4-5Ethanol resistance/4-5EA resistance/4Xylene resistance/4MEK resistance/3-4Application Company profile Exhibition Packing & DeliveryFAQ
