Applications

• Widely used in coatings, plastics, inks and other fields:
  • Coatings: Applicable to automotive coatings, industrial coatings, powder coatings, etc.
  • Plastics: Used for coloring plastics such as PVC (polyvinyl chloride), PS (polystyrene), PP (polypropylene), PE (polyethylene), PC (polycarbonate), and PET (polyethylene terephthalate).
  • Inks: Suitable for offset printing inks, water-based inks, etc.

Key Terminology Notes

• Diketopyrrolopyrrole (DPP) pigment: A high-performance organic pigment with a unique five-membered heterocyclic structure. It is known for bright color, excellent light fastness and weather resistance, and is widely used in high-end application fields such as automotive coatings and engineering plastics.
• Fastness Grade: A standard for evaluating the durability of pigments in use. Generally, the grade ranges from 1 to 8 (for light fastness) or 1 to 5 (for weather fastness, water fastness, etc.), where a higher grade indicates better durability (e.g., Grade 8 light fastness means almost no color fading under long-term light exposure).
• Powder coatings: A type of solvent-free coating that exists in powder form. It has the advantages of environmental protection (no volatile organic compounds) and high coating efficiency, and is commonly used in metal surface coating.
