Q1: What is the primary application of Hostatint UV BG Color Paste?
A: Hostatint UV BG Color Paste is a specialized pigment dispersion designed for coloring UV-curable coatings, inks, and adhesives—particularly where high color strength, excellent photostability, and minimal impact on cure speed are required.
Q2: Is this color paste compatible with common UV-curable resin systems?
A: Yes, Hostatint UV BG Color Paste is formulated for compatibility with standard acrylate-based UV resins—including monofunctional, difunctional, and multifunctional monomers and oligomers—as well as cationic UV systems, though compatibility testing under actual formulation conditions is recommended.
Q3: How should this paste be incorporated into a UV formulation?
A: It is typically added during the pre-mix stage under low-shear conditions to ensure homogeneous dispersion. Avoid high-shear mixing that may destabilize the pigment dispersion or introduce air entrapment detrimental to UV film quality.
Q4: Does Hostatint UV BG affect the UV curing performance of the final system?
A: When used within typical dosage ranges, it exhibits low interference with photoinitiator activity and maintains good surface cure and through-cure characteristics—however, optimal dosing depends on pigment loading, film thickness, and UV lamp output, so process validation is advised.
Q5: What are the key handling and storage recommendations?
A: Store in tightly sealed original containers at temperatures between 5 °C and 30 °C, protected from direct sunlight and freezing. Stir gently before use if sedimentation occurs; do not dilute with solvents unless validated for compatibility and stability.
