Q1: What is the primary application field for Hostajet Red D3G-PT VP 5121?
A: This pigment paste is specifically developed for use in water-based inkjet inks, particularly for industrial textile printing applications requiring high chroma, good lightfastness, and reliable jetting stability on reactive and acid dyeable substrates.
Q2: Is Hostajet Red D3G-PT VP 5121 compatible with common inkjet ink formulations?
A: Yes — it is formulated for compatibility with typical water-based inkjet systems, including those containing glycols, surfactants, and humectants. Compatibility testing under actual formulation conditions is recommended to confirm stability and performance.
Q3: How should this color paste be incorporated into ink formulations?
A: It is designed for direct addition during ink manufacturing, typically under low-shear mixing. Pre-dilution with deionized water or compatible vehicle may be used to aid dispersion. Avoid high-shear processing that could destabilize the pigment dispersion.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from freezing and direct sunlight. Stir gently before use if sedimentation occurs. Ensure proper workplace ventilation and refer to the Safety Data Sheet for handling guidance.
