Chemical Stability
Organic pigments are chemically stable, which means they do not react with other chemicals and remain unchanged over time. This stability makes them ideal for use in various applications as they retain their vibrant color for longer periods.
Lightfastness
Lightfastness refers to a pigment's ability to resist fading when exposed to light. Organic pigments generally have a high degree of lightfastness, which makes them suitable for use in outdoor applications or products that are exposed to sunlight.
Heat Resistance
Organic pigments can withstand high temperatures without losing their color intensity. This property makes them suitable for use in applications such as plastics, where the material is often subjected to high temperatures during processing.
Solubility
Organic pigments are typically insoluble in water, making them ideal for use in products that come into contact with water, such as textiles and coatings.they can be made water-soluble by the addition of certain chemicals, making them suitable for use in various water-based products.
Fast Yellow G (Pigment Yellow 1) is a monoazo structure environmentally friendly pigment yellow with good dispersibility and temperature resistance. The low price also determines its general application in powder coatings, but the lightfast yellow G The light resistance is in the 6-7 level, it is not recommended for outdoor products.
Permanent Yellow GG (Pigment Yellow 17), also known as Permanent Yellow 2G, is a green phase organic pigment yellow with high tinting power, high saturation, good solvent resistance and migration resistance, but Permanent Yellow 2G Discoloration occurs when the temperature exceeds 200 ° C, so it is not suitable for powder coatings with a baking temperature exceeding 200 ° C.
Permanent yellow HR (Pigment Yellow 83) belongs to red organic pigment yellow. According to the application, this pigment is generally divided into three types in China. One is transparent permanent yellow HR, which is cheap, has poor temperature and light resistance (light resistance 6-7, temperature resistance 180 degrees), and is mainly used in inks. Product; another, translucent permanent yellow HR, temperature and light resistance are better than transparency (light resistance 7 grade, temperature 180-190 degrees).
Pigment red 254, DPP red series, excellent pigment performance, temperature resistance of 300 degrees, light resistance level 8, can be used for relatively demanding outdoor powder coatings.
Size
The particle size of organic pigments is smaller than those of the inorganic pigments.
01
Brightness
Organic pigments exhibit more brightness. inorganic pigments are known for long-lasting effects as their stay in sunlight and chemicals is more than organic pigments.
02
Colors
Inorganic pigments have a more comprehensive range of colors as compared to organic pigments.
03
Cost
Inorganic pigments are cheaper and cost-effective.
04
Dispersion
The inorganic pigments exhibit better dispersion, for which they are used in several applications.
05
Paints and Coatings
In the paints and coatings industry, organic pigments are indispensable. They offer a wide range of color options, meeting both decorative and functional needs. One of the key characteristics of organic pigments is their vibrant colors, along with strong lightfastness and weather resistance, making them widely used in construction, automotive, furniture, and other fields.
Plastics and Polymers
Plastics and polymers are the core materials of modern industry, and organic pigments play a crucial role in this domain. By incorporating organic pigments into plastics, manufacturers can provide diverse color options and enhance the plastic products' resistance to light, heat, and chemical corrosion. This makes organic pigments widely applicable in household appliances, toys, packaging materials, and other plastic products.
Printing Inks
The printing industry demands high-quality colors, and organic pigments, with their vivid colors, excellent dispersibility, and resistance to heat and light, have become the primary components of printing inks. They are extensively used in the printing of books, newspapers, magazines, and various packaging materials, ensuring high-quality and long-lasting color performance in printed materials.
Textile Dyeing
Textile dyeing is one of the traditional application fields of organic pigments. They provide textiles with rich and long-lasting colors while maintaining the fabric's softness and breathability. Textiles dyed with organic pigments are commonly used in clothing, home textiles, and industrial fabrics, meeting consumers' high expectations for color and quality.
Art Supplies
Art creation requires pigments that are rich in color and durable, and organic pigments are widely used in artists' supplies such as oil paints, watercolors, and pastels due to their vibrant colors, ease of mixing, and excellent stability. These pigments help artists bring their creative visions to life, making them an indispensable tool in artistic creation.
Cosmetics and Personal Care Products
In the cosmetics industry, color is not only about aesthetics but also safety. Organic pigments are widely used in cosmetics, such as lipsticks, eyeshadows, and nail polishes. Due to their diverse colors, stable properties, and compliance with safety standards, organic pigments have become essential materials in cosmetic production.
Electronic Displays
In modern electronic products, organic pigments are extensively used in color filters for displays, especially in liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays. These pigments can precisely control color output, enabling displays to present vivid and accurate images.
Food and Pharmaceuticals
Certain natural organic pigments are used as colorants in food and pharmaceuticals. These pigments not only add appealing colors to products but also comply with safety standards for food and drugs. For example, natural organic pigments are often used to color candies, beverages, and the coatings of tablets, ensuring bright colors without compromising the product's quality and safety.
