1.Product Description
Pigment Yellow 12 (P.Y. 12) is an innovative high-performance disazo organic pigment, redefining industrial yellow coloring with its bright, vivid lemon yellow hue—vibrant yet not harsh, which perfectly caters to the diverse needs of mid-to-high-end industrial applications. Unlike traditional yellow pigments that suffer from dull color, poor dispersion, or high cost, our P.Y. 12 features a proprietary disazo synthesis and precision purification technology, delivering three client-centric advantages: a bright, uniform lemon yellow hue, excellent light fastness (Grade 6-7), and cost-effective performance—solving manufacturers’ pain points of dull yellow tones, easy fading, and high raw material costs.
Crafted with advanced low-temperature diazotization, coupling technology and multi-stage purification process, Pigment Yellow 12 boasts a uniform fine particle structure (specific surface area of 19 m²/g) that ensures excellent dispersion, eliminating agglomeration and sedimentation in various solvent-based formulations and plastic melts, greatly reducing production waste and improving coloring efficiency. Its 100% compliance with REACH, RoHS, and EINECS 228-787-8 standards (non-toxic, heavy metal-free, no harmful additives) adds an extra layer of value, making it suitable for consumer-facing products and eco-friendly industrial applications. What truly differentiates it is its balance of performance and cost—offering superior color vividness and fastness compared to ordinary yellow pigments, while maintaining a competitive price point.
Engineered for long-term reliability, P.Y. 12 boasts Grade 6-7 light fastness, with colored products retaining their vivid lemon yellow hue for more than 4 years under outdoor exposure, even when mixed with titanium dioxide for light color matching. It has good thermal stability (stable up to 180℃ for long-term processing), water resistance, oil resistance, and acid-alkali resistance (Grade 4-5), preventing color bleeding and fading in diverse industrial applications. With strong tinting strength, only 15-18% loading is needed to achieve standard color depth, significantly reducing raw material costs. It’s not just a yellow pigment—it’s a cost-effective, safety-compliant solution to elevate the aesthetics and durability of your industrial products, helping you gain a competitive edge in the market.

3.Product Application
Pigment Yellow 12 is a versatile, cost-effective disazo organic pigment, tailored to meet the specific needs of mid-to-high-end industrial sectors with its vivid lemon yellow hue, excellent fastness, and strong tinting strength. 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 Solvent-Based Printing Inks
Pigment Yellow 12 is a popular choice for solvent-based printing inks, including offset printing, gravure printing, flexographic printing, and screen printing. Its excellent dispersion capability ensures smooth ink flow, eliminating sedimentation and clumping even in high-speed printing (up to 700m/min), reducing production downtime and waste. With strong tinting strength and bright color saturation, only 15-18% loading is needed to achieve standard color depth, significantly cutting ink formulation costs. The vivid lemon yellow hue delivers sharp, vibrant prints with excellent color clarity, making it ideal for packaging printing, product labels, posters, and commercial printing. Its Grade 6-7 lightfastness ensures prints retain their vibrancy for years, even under outdoor exposure or frequent handling, avoiding the need for reprinting due to fading.
3.2 Industrial Coatings
Suitable for mid-to-high-end industrial coatings, including air-drying paints, baking enamels, and decorative coatings, Pigment Yellow 12 offers excellent compatibility with various solvent-based resin systems (alkyd, acrylic). Its uniform dispersion ensures even color distribution, creating a smooth, glossy finish without visible pigment particles. Its thermal stability up to 180℃ ensures consistent color during coating curing, while its acid-alkali resistance (Grade 4-5) prevents fading or discoloration from environmental pollutants and weak chemicals. The bright lemon yellow hue adds a lively, eye-catching touch to industrial products, architectural coatings, and metal protective coatings, combining aesthetics and long-term durability at a cost-effective price point.
3.3 Plastic Coloring
Applicable to plastic coloring, including rigid PVC, PP, PE, and ABS, Pigment Yellow 12 features excellent compatibility with plastic melts, ensuring uniform dispersion during injection molding and extrusion, eliminating streaking or color unevenness. Its thermal stability up to 180℃ meets the high-temperature processing requirements of most plastics, retaining its vivid lemon yellow hue without discoloration. With strong tinting strength, low loading is required, reducing raw material costs. It has good migration resistance, preventing color bleeding in plastic products, and its Grade 6-7 lightfastness ensures long-term color stability, making it ideal for plastic toys, household plastic products, electronic casings, and packaging plastics.
3.4 Textile Printing & General Stationery
In textile printing, Pigment Yellow 12 is suitable for solvent-based textile inks, especially for cotton, polyester, and blended fabrics. It delivers good color fastness (light fastness up to Grade 6-7, wash fastness up to Grade 4), retaining its vivid lemon yellow hue even after repeated laundering and outdoor exposure. Its bright color is popular in fashion and home textile products, and it can be mixed with other pigments to create diverse yellow shades. In general stationery, it is ideal for color pencils, crayons, markers, and office supplies, with good color fastness, no fading or smudging, and vivid coloration that appeals to consumers. Its cost-effectiveness makes it a preferred choice for large-scale stationery production.
