Use | The pigment gives a neutral or slightly blue red color, has a high tinting power (only 0.7% pigment concentration is required to reach 1/3SD) and excellent light fastness, mainly used for plastic and ink coloring; For polystyrene, polyurethane coloring, polypropylene pulp coloring, heat-resistant to 300 ℃ in HDPE, light-resistant to 7-8 (1/3s); high specific surface area dosage form (50-90 m2/g) can be used for high-grade printing ink, resist finish paint and sterilization treatment, used for metal decoration printing ink; Also used for architectural decoration coating. There are 23 types of products put on the market. |
