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.

Zirconium Nitride

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.

Why It Works

StructureFunctionMechanism
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.
