Q1: What is the primary chemical nature of Duasyn Black M-DL liquid pigment?
A: Duasyn Black M-DL is a high-performance, solvent-based liquid dispersion based on a modified carbon black pigment, stabilized with non-ionic surfactants to ensure excellent compatibility and long-term storage stability in polar organic media.
Q2: Is this pigment suitable for use in water-based systems?
A: Duasyn Black M-DL is specifically formulated for solvent-borne applications and is not recommended for direct use in water-based systems. For aqueous formulations, Clariant offers alternative liquid black pigments designed with hydrophilic stabilization systems.
Q3: How should Duasyn Black M-DL be incorporated into a coating or ink formulation?
A: It is typically added during the let-down or grinding stage using low-shear mixing. Pre-dilution with a compatible solvent may be used to facilitate uniform dispersion. Avoid high-shear processing that could destabilize the pigment dispersion.
Q4: What are the typical dosage ranges for achieving optimal blackness and opacity?
A: Dosage depends on the specific application requirements and desired shade intensity, but it is generally effective at low concentrations—typically ranging from 0.1% to 2% by weight relative to the total formulation.
Q5: Does Duasyn Black M-DL offer good resistance to thermal processing conditions?
A: Yes—it demonstrates robust thermal stability suitable for common industrial drying and curing processes encountered in coil coatings, industrial finishes, and certain plastic compounding operations below typical decomposition thresholds of the carrier system.
