Introduction

Pigment Red 170 F3RK is a high-performance organic pigment featuring a vibrant, clean neutral red hue and exceptional coloristic properties. Available in two crystal forms, it delivers outstanding versatility and reliability: the transparent type exhibits a blue-tinged red with lightfastness Grade 6, while the opaque type offers lightfastness Grade 7 and excellent hiding power. Both types boast strong solvent stability, along with resistance to acids, alkalis, soaps, and creams, paired with reliable thermal stability (200℃/10min) and superior weatherability. With a specific surface area of 23 m²/g (for Novoperm Red F2RK 70), it delivers high tinting strength, ensuring long-lasting color retention even in demanding environments.

Widely applicable in high-end coatings (compatible with molybdate orange and quinacridone for color matching), printing inks (transparent type recommended for metallic decorative inks), plastics (e.g., PP, polyacrylonitrile bulk coloring), pigment printing, wood coloring, and viscose fiber coloring, it provides consistent, high-quality performance across diverse premium application scenarios.
