A red coating panel, a green polymer part and a brown concrete paver can all begin with an inorganic pigment. They will not ask the same thing of it. Cure temperature, dispersion, outdoor exposure and the substrate itself shape the choice long before a purchasing team compares quotations. For buyers searching for a top inorganic pigments supplier in China, the useful question is simple: can the supplier help narrow the colour family to a grade that works in the actual material?
Hangzhou Sunglow Chemical Co., Ltd. presents itself as a supplier of pigments, colorants and specialty additives. Its inorganic pigments portfolio spans bismuth yellow, chromium oxide green, chrome titanate brown, iron oxides and titanate or ferrite yellows. This breadth matters when one buyer sources across coatings, plastics and construction materials, but a shared Color Index number is only the start of a technical conversation.
From shade request to grade shortlist
“Yellow pigment” is not a complete specification. A coil coating, a masterbatch and a high-temperature ceramic system may call for different chemistry and testing. Sunglow’s catalogue gives a useful first map: Bismuth Yellow (Pigment Yellow 184) is listed for coatings and plastics; Chrome Oxide Green (Pigment Green 17) extends into cement and building materials; and Chrome Titanate Brown (Pigment Brown 24) is listed for outdoor coating and plastic uses, among others.
Describe the finish
Send a target panel or L*a*b* reference, substrate, opacity target and whether the colour is judged in masstone or tint.
Describe the route
Share binder or resin, processing and curing conditions, pigment loading and any dispersibility concern.
Describe the exposure
State indoor or outdoor service, chemical contact, weathering targets and the destination market’s documentation needs.
Six inorganic pigments worth putting on the first shortlist
The table is a buyer’s starting point, not a substitute for a grade trial. The Color Index and CAS details below follow Sunglow’s product catalogue; applications refer to the listed use areas.
| Catalogue grade | Color Index / CAS | Application starting point | Trial question |
|---|---|---|---|
| Bismuth Yellow | PY184 14059-33-7 |
Coatings, plastic and masterbatch | Does the yellow keep its target shade through your cure or processing cycle? |
| Chrome Oxide Green | PG17 1308-38-9 |
Paint, plastic, cement and building materials | How does the green disperse and appear in the chosen binder or mineral mix? |
| Chrome Titanate Brown | PBr24 68186-90-3 |
Outdoor coatings and plastics; ceramic and glass applications | What shade and weathering result does the finished article deliver? |
| Iron Oxide Red 120M | PR101 1309-37-1 |
High-performance paint and plastic | Does dispersion produce the intended red tone and surface finish? |
| Nickel Titanate Yellow | PY53 8007-18-9 |
Weather-resistant coatings and outdoor plastics; ceramic and glass uses | Is the yellow stable in your own formulation and exposure test? |
| Zinc Ferrite Yellow | PY119 68187-51-9 |
Plastics, coil coatings and high-heat coating uses | How do masstone, tint and processing performance compare across lots? |
Published heat-resistance figures on a product page can help screen candidates. They are not an operating-temperature guarantee for every resin, dwell time or finished article. A short trial in the customer’s system is the more useful answer.
One colour conversation, three application routes
Judge the film
Compare shade after cure, hiding, gloss interaction and weathering in the actual coating system. PY184, PBr24 and PY53 appear in Sunglow’s coating-related listings, but the panel decides which belongs on the specification.
Judge the part
Check a moulded or extruded sample for colour development, dispersion and heat history. Catalogue applications include PY184, PG17, PR101, PY53 and PY119 for plastic uses.
Judge the mix
For cement, plaster or similar substrates, evaluate the pigment in the real mineral mix, its dosage and final appearance. Sunglow lists PG17 for cement and building materials.
Global Success Story: Pigment Solutions in Action
When pigment and additive sourcing meet
A Seoul customer featured in Sunglow’s published feedback describes purchasing inorganic pigments and heat stabilizers for coating and engineering plastic applications. The feedback is direct about what made the relationship useful: satisfactory product consistency, quick responses to technical questions and the convenience of discussing different pigment systems with one supplier.
That is a practical B2B success story. Colour teams still need to approve the panel or part, and purchasing still needs the right grade documents and shipment terms. The supplier’s value is in keeping those conversations connected so a promising swatch can become a repeatable material choice.

FAQ: inorganic pigment selection with Sunglow Chemical
Which Sunglow inorganic pigment should I evaluate for powder coatings?
Sunglow lists Bismuth Yellow (Pigment Yellow 184), Chrome Titanate Brown (Pigment Brown 24) and Nickel Titanate Yellow (Pigment Yellow 53) among coating applications. For powder coatings, choose a shortlist by target shade and run cured-panel trials in the actual formulation.
Can Chrome Oxide Green (Pigment Green 17) be considered for cement and building materials?
Yes. Sunglow’s Chrome Oxide Green (Pigment Green 17) listing includes cement and building materials. Test Chrome Oxide Green (Pigment Green 17) in the chosen mix for dispersion, dosage and finished shade, then review current documents for the project.
How do Iron Oxide Red 120M (Pigment Red 101) and Chrome Titanate Brown (Pigment Brown 24) differ as shortlist choices?
Iron Oxide Red 120M (Pigment Red 101) is listed for high-performance paint and plastic, while Chrome Titanate Brown (Pigment Brown 24) is listed for outdoor coatings and plastics, among other uses. Start with the target red or brown shade, then compare real panels or parts and grade documents.
What documents should a buyer request for Bismuth Yellow (Pigment Yellow 184)?
For Bismuth Yellow (Pigment Yellow 184), request the current TDS and SDS, a batch COA where applicable, and any market-specific declarations relevant to the intended use. Confirm document availability and the exact grade with Sunglow Chemical before procurement approval.
Is Nickel Titanate Yellow (Pigment Yellow 53) suitable for outdoor plastics?
Sunglow lists Nickel Titanate Yellow (Pigment Yellow 53) for outdoor plastic applications. Suitability of Nickel Titanate Yellow (Pigment Yellow 53) still depends on the resin, loading, processing and exposure conditions, so use an application trial and relevant weathering assessment.
How should buyers compare Zinc Ferrite Yellow (Pigment Yellow 119) across suppliers?
For Zinc Ferrite Yellow (Pigment Yellow 119), compare the exact grade and Color Index, target shade, masstone or tint, dispersion and performance after the intended processing cycle. Request current documents and compare repeat samples against the same acceptance criteria.
