How many azo pigment grades does Manali manufacture?

We manufacture over 60 organic azo pigment CI numbers, all synthesized entirely in-house at our manufacturing facility in India. Our comprehensive portfolio includes both monoazo and diazo pigments, covering a full spectrum of industrial colors ranging from vibrant reds and yellows to deep oranges and browns, serving printing inks, textiles, plastics, and coatings applications.

What is the difference between monoazo and diazo pigments?

Monoazo pigments are simpler molecules containing one azo group, offering excellent general-purpose properties including high tinting strength and bright shades at competitive cost. Diazo pigments possess a more complex molecular structure with two azo groups, which provides superior heat stability, enhanced lightfastness, and better migration resistance. We manufacture both types in-house to meet diverse application requirements.

Can I get a custom azo formulation?

Yes. Our integrated in-house R&D team works directly alongside our manufacturing division to develop custom azo formulations tailored to your specific needs. Whether you require enhanced heat stability for high-temperature plastics processing, improved dispersion characteristics for high-speed inks, or a highly specific shade match for your brand colors, we can engineer a solution.

What is the typical lead time for azo pigments?

Standard organic azo pigments from our existing portfolio are typically available for dispatch within 15-20 days from order confirmation. Because we control our own manufacturing schedules without dependency on external suppliers, we can often accommodate urgent requirements. Custom formulations generally require 4-6 weeks for comprehensive development, testing, and validation.

The Workhorse of Industrial Coloration

Organic azo pigments represent the single largest class of synthetic colorants used in industrial applications worldwide. Their unique combination of vibrant color strength, broad shade range, application versatility, and cost-effectiveness makes them indispensable across printing inks, textiles, plastics, and coatings. However, for ink formulators managing tight color tolerances and textile producers requiring repeatable fastness performance, the value of an azo pigment is only as good as its batch-to-batch consistency. Even minor variations in tinting strength, particle size distribution, or shade can cascade into costly production downtime, rejected lots, and reformulation cycles.

By manufacturing our entire organic azo portfolio in-house from raw material synthesis to final milling, Manali Pigments serves as the single-source solution that eliminates these risks entirely. We do not source azo pigments from third-party traders or contract manufacturers. Every gram is engineered within our own facility under controlled conditions, ensuring that each shipment performs identically to the last.

Understanding Monoazo & Diazo Pigments

Manali manufactures both major Monoazo pigments and diazo chemistries in-house, each engineered for a distinct performance profile.

Monoazo Pigments

Monoazo pigments contain a single azo chromophore group (-N=N-) linking aromatic ring systems. These simpler molecular structures deliver excellent general-purpose performance characterized by bright, clean shades and high tinting strength at competitive cost. Monoazo pigments are widely specified for architectural paints, standard printing inks, and general industrial coloration where moderate heat resistance is acceptable. Their ease of dispersion and strong color development make them the default choice for high-volume applications. Key monoazo grades manufactured in-house at Manali Pigments include Pigment Yellow 1, Pigment Yellow 74, Pigment Red 3, Pigment Red 112, and Pigment Orange 5.

Diazo Pigments

Diazo pigments (also called disazo or bisazo pigments) contain two azo groups within a larger, more complex molecular architecture. This increased molecular weight and structural complexity translate directly into superior heat stability, enhanced lightfastness, better migration resistance, and improved chemical resistance. These high-performance characteristics make diazo pigments essential for plastics processing at elevated temperatures, automotive coatings, and industrial applications demanding long-term outdoor durability. Manali manufactures a comprehensive range of diazo grades including Pigment Yellow 12, Pigment Yellow 13, Pigment Yellow 83, and Pigment Orange 34.

Comprehensive Color Index Reference

The Color Index (CI) system, maintained by the Society of Dyers and Colourists, provides a globally standardized method for identifying the exact chemical structure and performance properties of every commercial pigment. For procurement professionals and formulators, specifying pigments by CI number eliminates ambiguity and ensures you receive the precise chemistry your application requires. Below is a representative selection from our portfolio of 60+ in-house manufactured organic azo CI numbers with key performance data.

Engineered for Batch Consistency

Quality in organic azo pigments is ultimately defined by one metric: consistency. Because we manufacture 100% of our azo portfolio in-house, we enforce a rigorous testing regimen at every production stage that traders assembling products from multiple sources simply cannot replicate. Every batch undergoes systematic evaluation for tinting strength against reference standards, precise shade matching using spectrophotometric analysis, lightfastness under accelerated weathering, and heat stability at application-relevant temperatures. By controlling synthesis parameters in real-time and conducting over 100 specific quality tests per batch, we guarantee that the Pigment Yellow or Pigment Red you order today will perform identically to the batch you ordered last year. Our consistency rate of 99.8% ensures your formulations remain stable across production runs.
