Q1: What is the primary application field for Hostatint UV P2GL Color Paste?
A: Hostatint UV P2GL is specifically developed for UV-curable inks and coatings, including screen, inkjet, and flexographic formulations where high color strength, excellent dispersion stability, and minimal impact on cure speed are required.
Q2: Is this color paste compatible with common UV monomers and oligomers?
A: Yes — Hostatint UV P2GL is formulated to be compatible with standard acrylate-based UV systems, including mono- and multifunctional monomers (e.g., TMPTA, HDDA) and common epoxy or urethane acrylate oligomers. Compatibility should always be verified in the final formulation due to system-specific interactions.
Q3: How does Hostatint UV P2GL perform under UV exposure in terms of color stability?
A: The pigment system is selected and stabilized to deliver good lightfastness and UV resistance in cured films. While not intended as a UV stabilizer itself, it maintains consistent hue and minimal fading under typical indoor UV exposure conditions when properly formulated and cured.
Q4: What is the recommended dosage range for optimal performance?
A: Dosage depends on the desired shade intensity and substrate requirements, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in the final UV ink or coating formulation.
Q5: Does Hostatint UV P2GL require pre-dispersion or special handling before use?
A: No — it is supplied as a ready-to-use, pre-dispersed paste with optimized rheology for easy incorporation into UV formulations. Gentle mixing is sufficient; high-shear dispersion is not required, though compatibility and homogeneity should be confirmed in the target system.
