Cadmium Orange Pigment

High tint strength - Excellent opacity - Stable in most binder systems

Also listed and sold under the alias Pigment Orange 20

Cadmium Orange is characteristics of its high tinting strength, bright color,excellent light fastness, weather fastness and hiding powder, non Migratory, non bleeding.

Main Features

  • High tint strength — excellent color impact at low loading.
  • Good opacity — superior hiding in solvent and waterborne systems.
  • Weather & light resistance — suitable for exterior formulations with proper binder choice.
  • Factory direct — customizable milling and particle-size control.

Applications

Cadmium Orange is widely used in applications of plastics,masterbatches, rubber, leather as well as glazes, ceramics,construction materials.

Compatibility notes

Cadmium Orange (Pigment Orange 20) is broadly compatible with alkyds, acrylics, epoxies and most thermoplastics. For high-heat processing (e.g., injection molding) verify with a production trial. Check SDS for handling and any regulatory restrictions in your market.

Color matching & batch consistency

We provide batch-to-batch delta-E reports and ISO-style color certificates on request. For critical color jobs we recommend running a small pilot batch and requesting a pre-production sample.

Technical Guidance & Best Practices

To maximize color performance, we recommend: fine and controlled milling to achieve consistent particle-size distribution; use of appropriate dispersants for waterborne systems; pre-dispersing in a carrier such as propylene glycol or oleic-modified vehicles for certain inks. Avoid excessive shear that can release fines and reduce opacity.

Note:The data contained here are based on our current knowledge and experience. It is the responsibility of user to test our products before the final application.

Is Cadmium Orange the same as Pigment Orange 20?

Yes — Pigment Orange 20 is the common trade/industry alias used for this cadmium-based orange pigment. On all technical documents (TDS/SDS) you may see both names; we label our products with both to avoid confusion.

What safety and regulatory precautions should we consider?

Cadmium pigments contain heavy metals and are subject to local and international regulations. We do not provide regulatory advice; however, we supply SDS and can share typical handling, PPE, and recommended disposal procedures. For regulatory compliance (e.g., toy standards, RoHS, EU REACH) check applicable laws for the specific end-use and region.

How do you recommend dispersing Cadmium Orange for waterborne paints?

For waterborne systems use a non-ionic or anionic dispersant tailored to your binder chemistry, and mill the pigment with controlled energy to reach the target particle fineness. We offer a short technical guide and a recommended dispersant list tailored to acrylic latex systems—contact our technical team for the guide.

Do you offer alternatives with lower environmental concerns?

Yes — we can propose non-cadmium organic and inorganic orange pigments that mimic hue and tinting strength. These substitutes differ in opacity and lightfastness, so we provide side-by-side lab comparisons and field-weathering data to help you choose the best fit.

Can you produce custom masterbatches or micronized grades?

Absolutely. We offer custom milling, micronized powders, and masterbatches (PE, PP, PVC carrier). MOQ and lead time depend on grade and packaging—request a quote with your target application and loading.
