The use of pigments in the coating and printing ink industries has become increasingly widespread today. Choosing high-quality pigments plays a crucial role in determining a company’s business success. So, what are industrial pigments? How are they applied in the coating and ink industries? In this article, let’s explore pigments with Vichem to make informed, high-quality choices.
WHAT ARE INDUSTRIAL PIGMENTS?
Industrial pigments are chemical compounds made from colorants and processed into powder form. These compounds are widely used to add colour to coatings, inks, and other industrial applications. Pigments are notable for their rapid dispersion but do not dissolve in the dispersion medium.
In modern industries, powdered pigments are increasingly favoured for their ease of use, requiring no complex preparation or advanced expertise during the colouring process. Additionally, pigments are more cost-effective than other color forms, making them an optimal choice for businesses.
TYPES OF INDUSTRIAL PIGMENTS
Organic Pigments
Organic pigments are solid, powdered compounds containing organic colorants, such as azo pigments (-N=N-), phthalocyanine pigments [-C6H4(CN)2], anthraquinone pigments, and dye-based pigments. These chemical substances reflect colours through light wavelengths, enabling a wide range of vibrant hues. Organic pigments are commonly used in oil paints, delivering clear, vivid colours for perfect results. They are ideal for products related to rubber, plastics, pastes, and coatings.
Inorganic Pigments
Inorganic pigments are derived from coloured metals or insoluble metal salts, such as Cr2O3, TiO2, and iron oxides. Compared to organic pigments, inorganic pigments offer superior advantages, including heat resistance, UV resistance, and high colour durability. They are widely used in the paint and coating industry, providing long-lasting, weather-resistant finishes.
APPLICATIONS OF PIGMENTS IN COATINGS AND INKS
Pigments in Coatings
Pigments are used in coatings to create vibrant colours and enhance surface aesthetics. They improve coverage, conceal surface imperfections, and increase resistance to weather and UV rays, making coatings more durable in harsh environments.
Inorganic pigments, such as iron oxides and titanium dioxide, are highly favoured in coatings. They provide stable, fade-resistant colours, with titanium dioxide offering exceptional whiteness and coverage. These are ideal for both exterior and interior paints.
Pigments in Ink
In the printing ink industry, pigments ensure vibrant, sharp colours and are commonly used in offset, flexography, and digital printing. Pigments determine adhesion and print quality. Offset inks rely on pigments for high-quality prints, with inorganic pigments providing excellent durability and fade resistance. Digital printing inks require pigments with small, uniform particle sizes to ensure even distribution and sharp images.
TIPS FOR CHOOSING INDUSTRIAL PIGMENTS
Select the Right Pigment for Your Needs
Each type of industrial pigment serves specific applications. Inorganic pigments are ideal for exterior coatings due to their high durability and coverage. Organic pigments, with their vibrant colour reflection, are perfect for artistic paints, creating stunning, flawless artwork.
Avoid Overstocking Pigments
To optimize costs, some businesses purchase pigments in large quantities, hoping to benefit from bulk discounts. However, this practice can lead to significant drawbacks, including excess inventory, product waste, and potential degradation of pigment quality over time. To avoid these issues, carefully assess your production needs before ordering. Estimate the required pigment quantity based on project timelines, batch sizes, and expected usage rates. Regular inventory reviews and demand forecasting can further help balance supply and demand, preventing overstocking while ensuring availability.
Choose a Reliable Supplier
The industrial pigment market is diverse, but not all suppliers are trustworthy. Before purchasing, research thoroughly and select reputable suppliers offering products that meet international standards. This step is critical to ensuring safety and quality for optimal results.
