What is the difference between organic and inorganic pigments? The following is to explain for you:
1. pigments have soluble and insoluble, inorganic pigments and organic pigments are different. Inorganic pigments are generally mineral pigments, with inorganic pigments and colored earth and mineral pigments in the rock wall spray paint coating body changes humans have long known.
2, organic pigments are generally taken from plants and marine animals, such as Ancient Rome from the shellfish extracted from the clinoptilolite, garcinia cambogia, purple and so on. Pigment Red 166 is pure yellow-red. It is mainly used for coloring plastics and inks. It is not easy to remove in soft PVC. Has medium coloring power. Covering power. Very good light and weather resistance. Heat resistance up to 300°C in HDPE. Also used in polyacrylonitrile . Polystyrene and rubber coloring. Also recommended for high-grade industrial car paints, packaging inks and metal decorative inks. Pigment Red 242 quinuclidinone derivatives of pigment varieties have excellent migration resistance and excellent thermal stability, showing a pure blue-red or magenta color. The concentration of Pigment Yellow 139 does not affect the gloss, has excellent light resistance and weatherability; inorganic pigment to replace chrome yellow. It is suitable for high-grade paints (automobile refinishing paints), with light resistance up to grade 7-8. Pigment Red 185 is mainly used in high-grade automotive coatings (OEM), plastics and synthetic fibers for raw material coloring; in nitrocellulose (NC) Solvent ink, excellent coloring power (beyond C.I. Pigment Yellow 17), high gloss. Can be used for coloring plastics, paints, printing inks and coatings. Organic pigments have bright colors and strong coloring power; low density and non-toxic. Organic pigments look looser, while inorganic pigments are heavier. Organic pigments are generally more aesthetically pleasing and have higher coloring power than inorganic pigments.
3. Whether organic pigments cause chronic toxicity, especially carcinogenicity, is of great concern. Many organic pigments are insoluble in water and cannot be changed by the human body, but they can be adsorbed.
4. Organic pigments have been widely used as colorants for plastic consumer products. Toys and food packaging materials colorants.
5. Therefore, the possible effects of some trace impurities in the production of organic pigments on the application of the above consumer products need to be considered in addition to the toxicological and ecological properties of the pure pigments and the properties transferred from the above materials.
