Q1: What is the primary application of Hostatint UV D3GD Color Paste?
A: Hostatint UV D3GD is a highly concentrated, solvent-free color paste specifically developed for UV-curable inkjet inks and coatings used in industrial digital printing applications, including flexible packaging, labels, and decorative films.
Q2: Is this color paste compatible with common UV-curable resin systems?
A: Yes, Hostatint UV D3GD is formulated to provide excellent compatibility and dispersion stability in standard acrylate-based UV-curable systems, including monofunctional, difunctional, and multifunctional monomers and oligomers commonly used in inkjet formulations.
Q3: How should Hostatint UV D3GD be incorporated into a UV ink formulation?
A: It is typically added during the pre-mix stage under low-shear conditions, followed by high-shear dispersion or milling if required to achieve optimal particle deagglomeration and color uniformity. Avoid prolonged high-temperature processing to preserve photoinitiator compatibility and dispersion integrity.
Q4: Does this product contain volatile organic compounds (VOCs) or hazardous solvents?
A: No — Hostatint UV D3GD is a solvent-free, VOC-free color paste based on reactive dispersants and pigment concentrates, designed to support low-emission and environmentally responsible UV ink formulations.
Q5: What is the recommended dosage range for achieving target color strength?
A: Dosage depends on the specific pigment load, substrate, and desired opacity or chroma, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in the final ink formulation.
