Q1: What is the primary application field for Duasyn Black HEF-SF liquid pigment?
A: Duasyn Black HEF-SF is specially formulated for high-performance inkjet inks—particularly aqueous-based systems used in industrial digital textile printing on natural and blended fibers.
Q2: How does HEF-SF differ from other Duasyn Black liquid pigments?
A: The 'HEF-SF' designation indicates an optimized formulation for enhanced hydrolytic stability and superior filtration performance in fine-nozzle inkjet printheads, with reduced risk of nozzle clogging compared to standard HEF variants.
Q3: Is this pigment compatible with common inkjet ink additives such as humectants, biocides, and surfactants?
A: Yes—Duasyn Black HEF-SF liquid pigment is designed for compatibility with typical aqueous inkjet ink components, including glycols, triethanolamine, and non-ionic surfactants, though final compatibility should be verified under actual formulation and processing conditions.
Q4: What are the recommended storage conditions to maintain product stability?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from direct sunlight and frost. Avoid prolonged exposure to elevated temperatures or repeated freeze-thaw cycles to preserve dispersion integrity.
