Clariant Hostatint UV Black N 30 VP 6023 Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary application field for Hostatint UV Black N 30 VP 6023?

A: This pigment is specifically engineered for UV-curable inkjet inks and coatings, where high jetness, excellent dispersion stability, and strong UV absorption are required—particularly in industrial digital printing on rigid substrates such as plastics, metals, and coated papers.

Q2: Is Hostatint UV Black N 30 VP 6023 compatible with common UV-curable resin systems?

A: Yes—it demonstrates good compatibility with standard acrylate-based oligomers and monomers, including urethane acrylates, epoxy acrylates, and polyester acrylates. Optimal performance typically requires pre-dispersion using high-shear mixing or bead milling to achieve stable, low-viscosity pigment concentrates.

Q3: How does this pigment perform under prolonged UV exposure?

A: As a dedicated UV black pigment, it offers enhanced photostability in cured films compared to conventional carbon blacks—minimizing fading and maintaining color integrity during long-term outdoor exposure, especially when fully crosslinked within a robust UV matrix.

Q4: What is the recommended dosage range in UV ink formulations?

A: Dosage depends on formulation requirements and desired optical density, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in final ink systems—to balance jetness, rheology, and cure efficiency without compromising film flexibility or adhesion.

Q5: Does this product contain any heavy metals or halogenated compounds?

A: Hostatint UV Black N 30 VP 6023 is formulated to meet current industry expectations for restricted substances compliance; it contains no intentionally added heavy metals (e.g., lead, cadmium, mercury, or hexavalent chromium) or halogenated organic pigments, aligning with Clariant’s commitment to sustainable pigment solutions.
