6535-47-3 Usage
Description
Pigment Red 13 is an organic azo pigment obtained by the azo coupling of m-nitro-p-toluidine with the m-nitroanilide of β-hydroxynaphthoic acid. It is characterized by its dark red powder appearance and a bluish shade.
Uses
Used in Enamel Applications:
Pigment Red 13 is used as a coloring agent in air-dried and baked enamels, as well as truck body finishes. It provides good lightfastness and weather resistance, making it suitable for these applications.
Used in Paint and Coating Industry:
Pigment Red 13 is used as a pigment in the paint and coating industry due to its excellent acid and alkali resistance, as well as its heat resistance of 160°C minimum. Its properties make it a reliable choice for various coatings and finishes.
Used in Color Matching:
Pigment Red 13 is used for tinting purposes, with a tinging strength of 100-105%. This makes it a valuable component in the formulation of colored products, where accurate color matching is crucial.
Properties and Applications:
Pigment Red 13 exhibits good lightfastness with a rating of 6-7, and it has a specific surface area of 26 m2/g. It has a density of 1.60 g/cm3 and an oil absorption rate of 45-50%. The pigment also has a poor resistance to bleeding, with a rating of 4, and its water solubility is maximum 1.0%. Additionally, it has a residue on 80 mesh of 5.0% maximum and a volatile content of 1.0% maximum at 105 °C.

Check Digit Verification of cas no
The CAS Registry Mumber 6535-47-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,3 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6535-47:
(6*6)+(5*5)+(4*3)+(3*5)+(2*4)+(1*7)=103
103 % 10 = 3
So 6535-47-3 is a valid CAS Registry Number.
