1.Product Description
Pigment Red 48:2 (P.R. 48:2) is a high-performance azo-based strontium salt lake organic pigment, specialized in delivering bright scarlet coloration for industrial applications with excellent light fastness and dispersion—distinguishing itself from Pigment Red 48:1 (barium salt) with its strontium salt structure and superior compatibility with nitrocellulose resin systems. Unlike ordinary red pigments that suffer from poor light fastness or poor dispersion in ink formulations, our P.R. 48:2 features a precision diazotization-coupling and strontium salinization process, delivering three core advantages: a bright, eye-catching scarlet hue, excellent light fastness, and outstanding dispersion performance—solving manufacturers’ pain points of color fading, uneven dispersion, and poor compatibility with nitrocellulose-based inks.
Crafted with advanced low-temperature diazotization, coupling technology and high-purity strontium salinization purification process, Pigment Red 48:2 boasts a uniform fine powder particle structure (0.15–0.22 μm) and optimized dispersion performance, ensuring seamless integration into nitrocellulose-based printing inks, plastic melts, and industrial paint formulations. Its distinct scarlet hue offers a brighter, more vivid alternative to Pigment Red 48:1, elevating product aesthetics for packaging and stationery. Additionally, it is 100% compliant with REACH, RoHS, and EINECS 229-893-7, non-toxic, heavy metal-free, and suitable for diverse industrial applications, including high-end tobacco labels, wine labels, and nitrocellulose-based pre-dispersed pigment color chips.
Engineered for long-term reliability, Pigment Red 48:2 boasts Grade 4-5 lightfastness and thermal stability up to 200℃ (short-term processing), retaining its bright scarlet hue even after moderate outdoor exposure and high-temperature processing. Its excellent solvent resistance (resistant to esters, xylene, ketones, and common organic solvents) and good migration resistance effectively prevent color bleeding in plastic and ink formulations. With broad compatibility (especially with nitrocellulose resins), high tinting strength, and long-term durability, it is a versatile solution for ink, plastic, and paint industries, delivering consistent, vibrant scarlet results that meet the high standards of high-end packaging and stationery products—combining performance, compatibility, and aesthetics in one high-quality pigment.

3.Product Application
Pigment Red 48:2 is a versatile, high-performance organic pigment, tailored to meet the specific needs of printing ink, plastic, paint, and stationery industries with its bright scarlet hue, excellent light fastness, and superior compatibility with nitrocellulose resins. Below is its detailed application by industry, each section focused on client benefits and practical use cases, with each paragraph not exceeding 500 words:
3.1 Printing Inks
Pigment Red 48:2 is an ideal choice for solvent-based printing inks, especially nitrocellulose-based inks widely used in high-end tobacco labels, wine labels, and food packaging printing. Its excellent dispersion capability in nitrocellulose resin systems ensures smooth ink flow, eliminating sedimentation even in high-speed printing, and it can be well combined with ketone, acrylic, and polyurethane resin systems. The bright scarlet hue delivers sharp, vivid prints with good gloss, enhancing the visual appeal of packaging products. Its Grade 4-5 lightfastness prevents color fading, ensuring prints retain their vibrancy for a long time. With reliable performance and good solvent resistance, it is a preferred choice for high-end label and packaging printing, especially suitable for nitrocellulose pre-dispersed pigment color chips that require excellent dispersion and color stability.
3.2 Plastic Coloring
Suitable for high-end plastic coloring, including PVC (soft and hard), PE, and PP plastics, Pigment Red 48:2 features good compatibility with plastic melt formulations, ensuring uniform dispersion during injection molding and extrusion, eliminating streaking or color unevenness. Compared to Pigment Red 48:1, it offers a brighter scarlet hue, adding more visual appeal to plastic products. With high tinting strength, only 1.0% loading is needed to achieve standard color depth, significantly reducing raw material costs. Ideal for plastic parts, PVC products, and high-end plastic stationery, it retains its bright scarlet hue even after high-temperature processing and long-term use, with good migration resistance to avoid color bleeding in soft PVC applications.
3.3 Rubber Products
Applicable to rubber products, including rubber seals, rubber toys, and latex products, Pigment Red 48:2 features good compatibility with rubber formulations and excellent processing stability. It disperses uniformly in rubber during vulcanization, ensuring consistent color distribution without affecting rubber mechanical properties. Its thermal stability (stable below 200℃) ensures no color fading during vulcanization, meeting the processing requirements of most rubber products. The bright scarlet hue adds a vivid, appealing color to rubber products, while its non-toxic, eco-friendly properties comply with global rubber product safety standards, making it suitable for consumer-facing rubber products.
3.4 Industrial Paints & Stationery
Pigment Red 48:2 is suitable for industrial paints (metal protective paints, wood paints) and stationery coloring (color pencils, crayons). Its good dispersion in paint formulations ensures uniform color and good coverage, while its bright scarlet hue delivers an eye-catching finish. In stationery, it features good color fastness, resisting fading and smudging, making it ideal for high-quality color pencils and crayons. Additionally, it can be blended with other pigments to create custom red shades, expanding its application scope. Its superior light fastness and compatibility with various formulations make it a reliable choice for industrial paint and stationery manufacturers, delivering consistent, high-performance results.
