Product Introduction
C.I. Pigment Red 254, DPP Red 254, DPP Red DB, DPP Red 2030, DPP Red D-2
International Index Number: C. I. PIGMENT RED 254
Product Series: Pyrrole and Pyrrolidine Derivatives
CAS RN: 84632-65-5
C.I. Structure Number: 56110
Product Characteristics
Neutral Red Color Relative Density: 1.56 pH Value (10% Slurry): 7 Screen Residue 230 Mesh ≤ 0.1% Volatile Matter at 105° ≤ 1.0% Heat Resistance: 300℃/5min Product Application
Pigment Red 254 provides a perfect neutral red color, with excellent solvent resistance and light fastness reaching level 8. It is mainly used in automotive primers, and its flocculation can be improved by adding additives. To reduce costs, it can be blended with C.I. Pigment Red 170, which has a stronger blue light but lower light fastness, or with quinacridone to produce a non-transparent blue light red color. It can also be widely used for coloring plastics (PVC, PS, polyolefins, etc.), with heat stability of 300℃/5min in HDPE (1/3 SD).

How to test the coloring power of pigments
Pigment coloring strength, also known as actual strength, refers to the ability of a pigment to impart color. High coloring strength pigments can reduce the amount used during application, thereby increasing economic value, which is a significant consideration for users. For example, the coloring strength of Benzidine Yellow is very high, exceeding that of Chrome Yellow by 9 times, while Chrome Yellow is 3-4 times higher than Titanium Yellow. For instance, if the coloring strength of Lightfast Yellow G is set at 100, Lightfast Yellow 10G is only 48. The determination of pigment coloring strength is generally conducted between standard samples of the same variety. The coloring strength of the standard sample is set at 100%, and according to product standards, the test sample should not be lower than 95%. The determination method is similar to color comparison, where colored pigments are diluted with white pigments such as Zinc Barium White or Titanium White, and Zinc Oxide, followed by a comparison of coloring strength with the standard sample. When the coloring strength of the test sample is greater than or less than that of the standard sample, the amount of the standard sample can be adjusted to calculate the coloring strength percentage of the test sample. One method for intermediate control of determining coloring strength is to accurately weigh the test sample and standard sample, manually grind them with white ink containing 75% Zinc Oxide or 60% Rutile Titanium White, and calculate the coloring strength based on the amount of white ink consumed. This method is time-saving and labor-saving, and the results are quite accurate, but it is a non-standard determination method. A newer method for determining the relative coloring strength of pigments and the relative scattering strength of white pigments is to measure the absorption index of the prepared test sample and the standard sample using a spectrophotometer. The ratio of the two is expressed as a percentage, which represents the relative coloring strength. Similarly, after adding black pigment paste to white pigments, the scattering index of the test sample and the standard sample can be measured with instruments, and the ratio is expressed as a percentage, representing the relative scattering strength. The principles and determination methods can refer to the GB/T 13451.2-92 standard.
Shandong Yuhong produces organic pigments: Benzidine Yellow G, Permanent Yellow 2GS, Brilliant Red BK, Gold Red C, Permanent Orange F2G, Permanent Orange Yellow G, Lightfast Red, Lissol Red, and various shades of red, yellow, and orange pigments, which are applied in offset inks, solvent inks, water-based inks, printing pastes, plastics, paints, and other systems.
What are the types of organic pigments?
Classification and development overview of organic pigments, organic pigments have a wide variety of chromatographic types and different classification methods.
(1) Classified by their chromatographic colors: yellow-orange pigments, red (with yellow, green) pigments, purple, brown pigments, and green pigments.
(2) Classified by their application fields: pigments for coatings, pigments for inks, pigments for plastics (rubber), and pigments for cosmetics, which can be divided into four major categories.
(3) Classified by their chemical structure types, they can be divided into three major categories: azo, phthalocyanine, and heterocyclic.
