Product Features
- Excellent heat resistance — up to 1000°C, suitable for any polymer processing temperature.
- Excellent light and weather resistance — rated 8 for lightfastness, with long-term fade resistance outdoors.
- High Coverage — Opaque, excellent coverage for light-colored systems
- HDPE Injection Molding: No Warping — Excellent Dimensional Stability
- High Solar Thermal Reflectance (TSR) — Reduces heat buildup in outdoor light-colored products
- Low dust, free-flowing — easy to process with minimal particulates
- Eco-friendly & Safe — Lead-free, stable against sulfides; replaces leaded brass
- High value in blends — can replace part of titanium dioxide when compounded with organic pigments, reducing costs.
Application Areas
Plastic Coloring — Suitable for all polymers: LDPE, HDPE, PP, PVC, PS, ABS, PA6, PA66, PC, PBTAutomotive Interior Trim — Heat and Light Resistant, Color StableCoatings — Automotive, Industrial, Powder, Coil Coating, ArchitecturalRubber — Curing system stabilityLight-colored outdoor products — high TSR applications, such as building panels and outdoor furniture

Notes
- Please test with a sample first to confirm the optimal dosage and heat resistance conditions.
- The powder color chart may differ from the final product color. Please refer to the actual colored result.
- Evaluate weather resistance for long-term outdoor exposure.
- This product has slightly lower tinting strength than organic yellow pigments. For deep color applications, we recommend blending with organic pigments.
