1.Product Description
Pigment Red 48:3 (P.R. 48:3) is a high-performance azo-based strontium salt lake organic pigment, specialized in delivering blue-tinged red coloration for industrial applications with superior light fastness and optimal migration resistance in soft PVC—distinguishing itself from Pigment Red 48:1 (barium salt) and 48:2 (strontium salt variant) with its unique hue and outstanding plastic compatibility. Unlike ordinary red pigments that lack migration resistance in soft PVC or have poor light fastness, our P.R. 48:3 features a precision diazotization-coupling and strontium salinization process, delivering three core advantages: a unique blue-tinged red hue, Grade 6 light fastness, and the best migration resistance in soft PVC—solving manufacturers’ pain points of color bleeding in soft PVC, color fading, and uneven dispersion.
Crafted with advanced low-temperature diazotization, coupling technology and high-purity strontium salinization purification process, Pigment Red 48:3 boasts a uniform small flake-like particle structure (0.16–0.23 μm), a pH value of 7.0-8.5 (10% slurry), and optimized dispersion performance, ensuring seamless integration into plastic melts (especially PVC), solvent-based inks, and rubber formulations[1]. Its distinct blue-tinged red hue offers a unique aesthetic advantage over 48:1 (warmer) and 48:2 (brighter scarlet), elevating product differentiation. Additionally, it is 100% compliant with REACH, RoHS, EINECS 239-879-2, non-toxic, heavy metal-free, and approved for use in food packaging materials, suitable for diverse high-end industrial applications.
Engineered for long-term reliability, Pigment Red 48:3 boasts Grade 6 light fastness (0.2% transparent concentration), which is 3 grades higher than 48:1 and 0.5-1 grade higher than 48:2 and 48:4, retaining its blue-tinged red hue even after long-term outdoor exposure. It has thermal stability up to 200℃ (short-term processing), excellent solvent resistance (resistant to esters, xylene, ketones, and common organic solvents), and the best migration resistance in soft PVC among the 48 series pigments. With broad compatibility (especially with PVC), high tinting strength, and compliance with food packaging standards, it is a versatile solution for plastic, ink, and rubber industries, delivering consistent, high-performance blue-tinged red results.

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.
