What is ZrN?
Zirconium Nitride (ZrN)
Fine zirconium nitride black pigment for UV-curable films, adhesives, paints, and coatings that require UV transmission with visible-light shielding.
Technical owner: Aurexene Materials Engineering Team · Last updated: 2026-07-26
What It Is Not
- ZrN is zirconium nitride, not TiN titanium nitride or zirconia.
When Not to Use It
- Do not use ZrN when the selected grade cannot meet the required UV-cure wavelength, visible-light shielding, film appearance, dispersion, or adhesion target.
- Do not position this grade as an IR-shielding, generic optical-black, or laser-marking material without application-specific evidence.
Intrinsic Screening Summary
- Identity screen
- ZrN (zirconium nitride); Fine black zirconium nitride pigment powder; dispersion-liquid form may also be available
- Intrinsic feature
- The finished film must be measured at its specified UV-cure wavelength, pigment loading, thickness, resin, photoinitiator package, and substrate; powder identity alone does not establish a cure window or optical performance.
- Material-level integration
- Establish dispersion quality, loading, film thickness, cure dose, through-cure, adhesion, visible-light shielding, and final appearance in the intended adhesive, paint, or coating.
Application Fit
| Application | Suitability | Conditions | Limitations |
|---|---|---|---|
| UV-curable adhesive | BENCHMARK EXAMPLE OF USE | UV transmission at cure wavelength, degree of cure, adhesion, visible-light shielding, color, haze, and aging results for the final bondline. | Verify the exact pigment form, loading, film thickness, resin, photoinitiator, substrate, and UV source. |
| UV-curable paint or coating | BENCHMARK EXAMPLE OF USE | UV transmission at cure wavelength, cure response, film thickness, visible-light shielding, appearance, adhesion, and durability results. | Verify the exact pigment form, loading, resin, photoinitiator, substrate, and UV source. |
| Display and optical-component light shielding | BENCHMARK EXAMPLE OF USE | Wavelength-specific transmission and shielding, coating uniformity, adhesion, and environmental stability for the assembled component. | Measure stray-light suppression separately when it is a system requirement. |

Why It Works
| Structure | Function | Mechanism |
|---|---|---|
| Fine black zirconium nitride pigment, 20-50 nm primary particle diameter for the benchmark grade. | Enables visible-light shielding while allowing UV transmission in qualified UV-curable films. | The finished film must be measured at its specified UV-cure wavelength, pigment loading, thickness, resin, photoinitiator package, and substrate; powder identity alone does not establish a cure window or optical performance. |
