Q1: What is the primary application of Hostatint UV N30 Color Paste?
A: Hostatint UV N30 is a solvent-free, UV-curable color paste designed for use in UV-curable inks, coatings, and overprint varnishes—particularly where high color strength, excellent dispersion stability, and minimal impact on cure speed are required.
Q2: Is Hostatint UV N30 compatible with common UV resin systems?
A: Yes, it is formulated to be compatible with standard acrylate-based UV oligomers and monomers, including urethane acrylates, epoxy acrylates, and polyester acrylates. Compatibility testing under actual formulation conditions is recommended prior to full-scale use.
Q3: How should Hostatint UV N30 be incorporated into UV formulations?
A: It is typically added during the final mixing stage under low-shear conditions to avoid air entrapment. Pre-dispersion is not required, but thorough homogenization ensures optimal color uniformity and performance.
Q4: Does Hostatint UV N30 contain volatile organic compounds (VOCs) or hazardous solvents?
A: No—it is a solvent-free, 100% solids color paste, formulated without aromatic hydrocarbons, chlorinated solvents, or regulated VOCs, supporting low-emission UV formulation strategies.
Q5: What storage conditions are recommended for optimal shelf life?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from direct sunlight and moisture. Avoid freezing, and ensure lids are tightly closed after each use to prevent skinning or viscosity changes.
