In the world of paint, choosing the right pigment has a direct impact on the quality, durability, and beauty of the final color.
At Nilichem, as a specialized manufacturer of various inorganic and organic pigments, we have been providing precise and practical solutions for years alongside paint and coating manufacturers.
Read our comprehensive guide on pigment application in various sectors of the masterbatch industry below.
If needed, you can benefit from our consulting services for a more accurate selection.
Pigments are added to masterbatches to create a uniform, consistent color in polymer products. Adding pigment makes the final product uniform and looks very attractive and professional, and prevents unwanted stains or color changes.
Pigments help to provide stability and protection against damaging environmental influences such as UV rays from the sun, heat, and moisture. This feature helps the product to remain stable and not change color or fade. This feature is especially important for products that are exposed to direct sunlight.
Using masterbatches that contain pigments instead of colored powders reduces dust and mixing problems on the surface, which greatly helps increase the quality and speed of production. It also improves employee health.
Pigments allow for the production of a variety of special colors, such as metallic, opaque, transparent, fluorescent, and even colors with optical effects. This variety of colors allows manufacturers to market different and more attractive products with diverse appearance characteristics.
Before we get into the details, it is important to understand what a masterbatch is. A masterbatch is a high concentration of a pigment or additive dispersed in a polymer base and formed into a grain or granule. Imagine that instead of adding a very fine, dispersed colored powder to the polymer, you melt the same powder into a small amount of plastic and form it into smaller granules.
Advantages of Using a Masterbatch:
Uniform distribution and perfect final color
Precise control of color and properties
Reduce dust and improve safety
Increase production efficiency and reduce waste
Improve physical properties of the final product
At Nilgun Pigments, we produce pigments with high quality, color stability, and environmental sustainability using precise formulations and advanced equipment. The pigment production process depends on its type (organic or inorganic), but the general principles are as follows:
Inorganic pigments are mainly derived from metal compounds and are widely used in various industries due to their high resistance to light, heat and chemical reactions.
The steps in the production of inorganic pigments include the following:
🔹Selection of raw minerals: Using metals and oxides such as iron oxide, chromium, titanium and manganese as the main base
🔹Milling and granulation: Reducing particle size in order to achieve uniform distribution in polymer or pigment media
🔹High-temperature calcination: Heating inorganic compounds in the range of 800 to 1200 degrees Celsius to form resistant crystalline structures
🔹Cooling and separation: Controlling the final particle size and removing impurities using physical methods
🔹Applying surface coating (if required): To improve compatibility and dispersion in water- or oil-based formulations
This process produces pigments with high stability and optimal performance in harsh environmental conditions.
Organic pigments are made from complex organic structures and are widely used in the decorative, printing and automotive industries due to their brilliance, transparency and high color variety.
The steps in the production of these pigments include:
🔹Chemical synthesis: Production of a color structure through a chemical reaction between organic derivatives such as azo compounds, phthalocyanines, or indolines
🔹Precipitation: Separation of the color compound from the reaction solution by creating a pure precipitate
🔹Washing and filtration: Removal of impurities to obtain a pure and high-quality pigment
🔹Drying and grinding: Conversion of precipitates into soft and uniform powders to improve dispersibility in various environments
🔹Surface coating operations (if needed): In order to increase the durability of the pigment, prevent caking, and optimize compatibility with resins or solvents
These processes allow organic pigments to perform flawlessly in sensitive applications and to show an attractive appearance.
At all stages of production, rigorous tests are carried out to control the following:
Hiding Power
Light and Thermal Stability
Particle Size and Distribution
Compatibility with Water and Oil Based Systems
Heavy Metal Content (for Sensitive Uses)
