The list is comprised exclusively of organic and inorganic colour pigments identified by the standard industry designations such as Pigment Yellow 1, Pigment Yellow 83, Pigment Red 2, Pigment Red 48:1 and related series. Each entry follows the nomenclature used in the global pigment market, enabling easy cross‑reference with technical data sheets. The supplier’s catalogue is organised by colour families (yellow and red) and includes both single‑toner pigments and mixed‑toner grades that are common in coatings, plastics and printing inks.

The products fall under the HS Chapter 32 heading 3206.90, which covers organic pigments and preparations. Typical specifications for these pigments include a colour strength (tinctorial power) expressed in ISO 7876, purity levels of 95 %  -  99 %, particle size distribution between 10 µm and 30 µm, and oil absorption values ranging from 45 g to 80 g per 100 g pigment. Buyers often request compliance documentation such as REACH registration, MSDS, and batch‑specific analytical reports. The catalogue does not mention any proprietary certifications held by the supplier.

Product Range and Specialties of Zhejiang Shengda Charter Win Chemical Co., Ltd.

The catalogue enumerates 30 distinct pigment designations, split between yellow (e.g., Pigment Yellow 1, 83, 97, 151, 154, 183, 12, 3, 14) and red (e.g., Pigment Red 2, 3, 4, 8, 21, 22, 48:1‑4, 49:1‑2, 112, 122, 146, 169). These designations correspond to well‑known colour standards used in the plastics, automotive coatings and printing ink sectors. Typical industry grades for these pigments are classified by colour index (C.I.) numbers, with purity specifications of 95 %  -  99 % and colour strength values that meet ISO 7876‑2 requirements. Particle size is usually controlled to 10‑30 µm to ensure good dispersion, and oil absorption is reported in grams per 100 g pigment to aid formulation calculations.
