1.Product Description
Pigment Red 170 F3RK (P.R. 170 F3RK) is an innovative high-performance naphthol-based organic pigment, redefining blue-shaded red coloration for modern industrial applications with its unique transparent texture and vivid hue—distinct from warm scarlet red pigments like P.R.254. Unlike ordinary red pigments that lack solvent stability or compromise transparency for color vibrancy, our P.R.170 F3RK features a proprietary F3RK crystal modification process, delivering three client-centric advantages: a stunning blue-shaded red hue, exceptional solvent resistance, and high transparency—solving manufacturers’ pain points of color bleeding, poor compatibility, and limited application scenarios.
Crafted with advanced low-temperature azo coupling technology, Pigment Red 170 F3RK boasts a uniform rod-shaped particle structure (0.18–0.22 μm) and high specific surface area (22–26 m²/g), ensuring seamless integration into solvent-based, aqueous, and plastic melt formulations, even in high-speed processing. Its distinct blue undertone sets it apart from conventional red pigments, offering a cool, elegant color that elevates product aesthetics, while its optimized particle size reduces loading requirement by 18% compared to standard P.R.170 variants—directly cutting raw material costs. Additionally, it is 100% compliant with REACH, RoHS standards and EINECS 220-509-3, non-toxic, heavy metal-free, and suitable for diverse high-end applications.
Engineered for long-term reliability, Pigment Red 170 F3RK boasts Grade 6–7 lightfastness (transparent type: Grade 6; non-transparent type: Grade 7) and thermal stability up to 200°C (10min tolerance) and 180°C (30min tolerance), retaining its vivid blue-shaded red hue even after prolonged UV exposure and high-temperature processing[superscript:2]. Its excellent solvent stability (resistant to alcohols, esters, xylene and other organic solvents) prevents color bleeding and migration, ensuring consistent color in end products[superscript:3]. With broad compatibility and high tinting strength, it is a versatile one-stop solution for diverse industries, delivering consistent, eye-catching results that set your products apart—combining innovation, stability, and cost-efficiency in one high-performance blue-shaded red pigment.

3.Product Application
Pigment Red 170 F3RK is a versatile, high-value organic pigment, tailored to meet the specific needs of diverse industries with its unique blue-shaded red hue, high transparency, and exceptional solvent stability. Below is its detailed application by industry, each section focused on client benefits and practical use cases:
3.1 Printing Inks
Pigment Red 170 F3RK is a top choice for high-end solvent-based and aqueous printing inks, including offset, gravure, digital, and metal printing inks. Its high transparency and excellent solvent stability eliminate color bleeding and sedimentation, ensuring smooth ink flow even in high-speed printing. With high tinting strength, only 15% loading is needed to achieve standard color depth, reducing ink formulation costs significantly. The blue-shaded red hue delivers sharp, elegant prints with excellent clarity, making it ideal for luxury packaging, brand logos, and polyester film decorative printing, while its good lightfastness ensures long-lasting vibrancy under various conditions.
3.2 Automotive & Industrial Coatings
Perfect for automotive basecoats, touch-up paints, architectural coatings, and metal coatings, Pigment Red 170 F3RK offers excellent compatibility with solvent-based and water-based coating systems. Its high transparency and good flowability allow for increased pigment concentration to enhance coverage without affecting gloss, making it ideal for automotive and industrial finishing. The blue-shaded red adds a cool, premium aesthetic to coatings, while its thermal stability and chemical resistance prevent fading, chalking, and corrosion—ensuring long-lasting color retention in harsh outdoor and industrial environments.
3.3 Plastics
Suitable for engineering plastics (PP, PE, PVC, ABS), Pigment Red 170 F3RK features excellent compatibility and low migration. Its uniform particle size ensures uniform color distribution during injection molding and extrusion, eliminating streaking or color unevenness. It performs well in rigid PVC coloring, while being suitable for non-light-colored soft PVC products (avoiding slight bleeding in light shades). Its high solvent stability prevents color migration in plastic processing, ensuring consistent color in end products like plastic parts, toys, and decorative accessories, while its low loading reduces formulation costs.
3.4 Textiles & Decorative Colorants
Applicable to water-based and solvent-based textile printing pastes for cotton, polyester, and blended fabrics, Pigment Red 170 F3RK delivers excellent wash fastness and rub fastness, retaining its blue-shaded red hue even after repeated laundering. It is also suitable for decorative colorants (ceramic glazes, candle wax) and high-end art supplies, offering a blendable, transparent tone that appeals to professional artists and hobbyists. Its eco-friendly formulation and good compatibility make it a reliable choice for diverse decorative and textile applications.
