What role do organic pigments play in powder coatings?
2024 / 02 / 29
Organic pigments play several roles in powder coatings: 1. Color effects: Organic pigments can give powder coatings rich color effects, making them attractive and decorative. Different organic pigments can produce different colors and shades to meet the needs of different customers. 2. Covering power: Organic pigments can provide good covering power so that the powder coating can effectively cover the color and surface defects of the substrate. This is important for applications where it is necessary to hide substrate imperfections or change the color of the substrate. 3. Light Resistance: Organic pigments provide good light resistance so that powder coatings are less likely to fade or discolor under prolonged exposure. This is important for outdoor applications or products that require long term color stability. 4. Chemical resistance: Organic pigments can provide a certain degree of chemical resistance, so that the powder coating can resist the erosion and corrosion of some chemical substances. This is very important for the application of some special environments, such as chemical plants, marine equipment. 5. heat resistance: organic pigments can provide a certain degree of heat resistance, so that the powder coating can maintain color stability and performance at high temperatures. This is very important for products that need to be used in high temperature conditions, such as automobile hoods, baking paint equipment, etc. 6. Weatherability: Organic pigments provide a degree of weatherability that enables powder coatings to maintain color stability and performance in harsh climatic conditions. This is important for outdoor applications or products that require long-term exposure to the natural environment. In short, organic pigments play a variety of roles in powder coatings, such as color effect, hiding power, light resistance, chemical resistance, heat res
Physical Properties and Color of Organic Pigments on Coating Performance
2024 / 01 / 29
The size of organic pigment particles has a great influence on the color performance of coatings. On the one hand, it affects the covering power and coloring power of the paint, within a certain range of pigment particle size, the covering power of the paint increases; when the pigment particles become small, the specific surface increases, and the coloring power of the paint increases. Pigment particle size also has an effect on the color light of the paint, usually the particle size is large, the particle size distribution is wide, the color light is dark; on the contrary, the color light is bright. On the other hand, pigment particle size also affects the UV resistance of paint. When the particle becomes small, the specific surface area increases, the absorbed light energy increases, the degree of destruction also increases, so the paint fades faster. Pigment particle size is small, the gravity is small, the paint is not easy to stratify and precipitate; but the pigment with small particle size has large specific surface area, the surface energy increases so that the chance of flocculation and roughness of the paint increases, which is not conducive to grinding and dispersion. Most organic pigments exist in crystal state, and the phenomenon of "homogeneous heterocrystal" is very common. Copper phthalocyanine crystal, common Q-type red blue (such as pigment blue 15) poor stability, after specific solvent treatment is turned into a stable P-type green blue (such as 15:3); pigment violet 19 (quinolone structure) has α, β and γ 3 kinds of crystal, α-type has no value, β-type for the purple-red, and γ-type for the blue red. In the design of coating formulations, pay attention to the rational use of additives and solvents to prevent different crystal types from transforming under certain conditions, which will cause the coating to undergo chromatic drift and make it difficult to find the right color acco

Color Matching Tips for Powder Coatings
2024 / 01 / 24
Ⅰ. What color: Color is an optic nerve sensation when the human eye is stimulated by radiation of a certain wavelength and intensity. Although colors vary, there are only three basic colors: red, yellow and blue, often referred to as the three basic colors. Two equal primary colors are mixed to form secondary (intermediate) colors, which are equal to the primary colors to form composite colors. Pigments are usually determined by three parameters: hue, saturation and brightness, also known as the color triad. Monochromatic color without adding other colors as pure color, adding other colors as intermediate color or compound color. Two coated workpieces of the same color present different colors and colors under different light or sunlight. This is the essence of brightness with a certain hue and intensity, which is the difference in saturation. Ⅱ. the color formula. Generally speaking, this powder coating is mainly some inorganic pigments, pigment color durability is good, the cost is relatively low; in addition, inorganic coatings bright colors, high coloring power, high cost. Depending on the cost, the light resistance of the paint produced is also high, but the price will be expensive. The standard formula can be debugged according to the brightness of the color sample. Ⅲ.powder coating color mixing skills. Pigments used for powder coatings can be classified according to production method, composition structure, function and other methods. 1. Pigments are classified according to production methods. According to the production method, it can be divided into natural pigment and synthetic pigment. Powder coatings usually use less natural pigments. Synthetic pigments include titanium dioxide. Iron oxide series. Phthalocyanine series. Azo. Polycyclic pigments and so on. 2. Function distinction. According to the func
Classification and characterization of pigments
2024 / 01 / 23
Pigment is an important and indispensable element in painting and decorative arts. According to their classification and characteristics, pigments can be divided into two categories: inorganic pigments and organic pigments. Inorganic pigments are made of natural minerals or synthetic inorganic substances. These pigments have strong stability and durability and are not easily affected by light, oxidation and chemical reaction. Common inorganic pigments include iron oxide yellow, titanium dioxide, graphite, limestone and so on. Iron oxide yellow is a yellow pigment with good covering power and durability, commonly used in oil and watercolor paintings. Titanium dioxide is a white pigment with very high covering power and gloss, commonly used in oil painting, watercolor painting and wall coating. Graphite is a black pigment with good conductivity and lubricity, often used in pencil lead and drawing. Limestone is a white pigment with good covering and adsorption properties, often used in murals and pastels. Organic pigments are pigments made from organic compounds. These pigments have rich colors and good transparency, but they are less stable and durable compared to inorganic pigments. Common organic pigments include phthalocyanine blue, azo yellow and phthalocyanine green. Phthalocyanine blue is a kind of blue pigment with bright color and good transparency, commonly used in oil painting and watercolor painting. Azo yellow is a yellow pigment with good covering power and stability, commonly used in oil painting, watercolor painting and printing. Phthalocyanine green is a kind of green pigment with bright color and good transparency, commonly used in oil painting, watercolor painting and plastic products. Besides the above two types of pigments, there is a special type of pigment, i.e. metallic pigment. Metallic pigments are pigments made of metal flakes or metal powder with unique metallic luster and
Advantages and Challenges of Organic Pigments in Dyeing Plastic Products
2024 / 01 / 22
Organic pigments offer many advantages in the coloring of plastic products, but also face a number of challenges. Organic pigments are pigments made from organic compounds with complex molecular structures that offer a wide range of color options. The advantages and challenges of organic pigments in dyeing plastic products are described in detail below. First of all, one of the advantages of organic pigments in dyeing plastic products is the diversity of color options. Organic pigments can change color by adjusting the molecular structure, thus providing many color options to meet the needs of different customers. This diversity makes plastic products more competitive in the market and can attract more consumers' attention. Secondly, organic pigments have good light resistance and weather resistance in the dyeing of plastic products. The aromatic ring structure in the organic pigment molecule can absorb ultraviolet light, thus reducing the possibility of color fading and yellowing of plastic products. This lightfastness and weatherability allows plastic products to maintain long-lasting color stability in outdoor environments, extending their service life. In addition, organic pigments have good chemical resistance in the dyeing of plastic products. The bonds in the molecular structure of organic pigments are able to form strong chemical bonds with plastic molecules, thus improving the bonding force between the dye and the plastic. This chemical resistance makes plastic products less likely to fade or change color when exposed to chemicals, increasing their reliability in a variety of applications. However, organic pigments face some challenges in coloring plastics. The first is the relatively high price of organic pigments. Organic pigments are complicated to prepare and cost more to produce, making them more expensive. This increases the cost of organic pigments in the dyeing process and has an im
Structural classification of organic pigments
2024 / 01 / 19
Organic pigments are pigments made of organic compounds whose color comes from the conjugated system or aromatic ring structure in the molecular structure. According to their different molecular structures, organic pigments can be divided into three categories: azo pigments, phthalocyanine pigments and aromatic pigments. 1. Azo pigment Azo pigment is one of the common organic pigments, which contains azo group (-N=N-) in its molecular structure. The color of azo pigment depends on the position of azo group, the type and number of substituents and other factors. The common azo pigments are yellow No.4 for orange color, red No.3 for red color, blue No.1 for blue color and so on. 2. Phthalocyanine pigment Phthalocyanine pigment is a kind of organic pigment containing phthalocyanine structure, which contains four pyrrole rings and one benzene ring in its molecular structure. The color of phthalocyanine pigment depends on the substituent group on the benzene ring and the type of metal ion on the pyrrole ring. Common phthalocyanine pigments include green copper phthalocyanine, blue cobalt phthalocyanine and so on. 3. Aromatic pigments Aromatic pigment is a kind of organic pigment which contains aromatic ring structure, and its molecular structure contains benzene ring, naphthalene ring, anthracene ring and so on. The color of aromatic pigment depends on the type and number of substituents on the aromatic ring. Common aromatic pigments include yellow aniline yellow, red red F3RK and so on. In conclusion, the structural classification of organic pigments mainly includes three categories: azo pigments, phthalocyanine pigments and aromatic pigments. Different organic pigments have differences in molecular structure, so their colors are different. Organic pigments have the advantages of bright color, light resistance,

Pigments and Dyes – The Chemistries Are Not the Same
2022 / 10 / 28
Written by David Wawer, Executive Director, CPMA A recent surge in announcements by a variety of researchers show the discovery of alternative, non-traditional methods to producing pigments. Some of the claims are that these new pigments are [greener" than their traditional counterparts. These claims are both exciting and intriguing. A recent article in GreenBiz described the Biomimicry Institute`s Ray of Hope Prize to Swiss company, Impossible Materials, for research on natural substitutes for Titanium Dioxide (TiO2)[1]. The article stated [A Switzerland-based company Impossible Materials looked to the brilliantly white Cyphochilus Beetle for the inspiration for an alternative. They found that its body has structures that diffuse light waves, making it completely white. The company`s design team created a similar structure out of cellulose waste that produces a white pigment and, according to Yarnall-Schane, creates a brighter white than titanium dioxide and will also be cheaper at scale." The article neglects, however, to accurately differentiate between a dye and pigment. In using the two words interchangeably, the authors fail to recognize that pigments and dyes chemistries are not the same. TiO2 is commonly known by industry experts as [white pigment" and is not a dye. The company research project references TiO2 as [white dye". Pigments industry experts define dyes as [soluble" chemistry, and pigments as [insoluble" chemistry. The Color Pigments Manufacturers Association (CPMA) is the acknowledged resource for regulatory, technical, and scientific information about the color pigments value chain and color pigments chemistry. CPMA representatives provide information to industry trade publications, state and national governments officials, downstream customer industries, and others. Public inquiries about color pigments science and technology have included inquiries from academic institutions conducting research on innovation for pigments products.
