Q1: What is the primary application of Hostatint UV H3G Color Paste?
A: Hostatint UV H3G Color Paste is specifically designed for coloring UV-curable inks, coatings, and adhesives where high photostability, excellent dispersion, and minimal impact on cure speed are required.
Q2: Is this color paste compatible with common UV resin systems?
A: Yes, Hostatint UV H3G is formulated to be compatible with a broad range of acrylate-based UV resins, including mono-, di-, and multifunctional monomers and oligomers, without causing premature gelation or significant viscosity increase.
Q3: How should Hostatint UV H3G be incorporated into UV formulations?
A: It is recommended to add the paste under low-shear mixing conditions after the main resin components are combined, followed by gentle homogenization. Avoid high-shear dispersion unless validated, as it may affect pigment integrity or rheology.
Q4: Does this product contain volatile organic compounds (VOCs) or solvents?
A: Hostatint UV H3G is a solvent-free, high-pigment-strength paste based on reactive or non-volatile dispersants, making it suitable for low-VOC and high-solids UV formulations.
Q5: What is the typical dosage range for achieving target color strength?
A: Dosage depends on formulation requirements and desired opacity/tinting strength, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the total formulation.
