Q1: What is the primary application of Duasyn Ink Blue SLK pigment?
A: Duasyn Ink Blue SLK is specifically developed for use in high-performance ink systems, particularly water-based and solvent-based gravure and flexographic inks for packaging applications where excellent tinctorial strength, gloss, and dispersion stability are required.
Q2: Is this pigment suitable for food packaging inks?
A: Yes — Duasyn Ink Blue SLK is designed to meet stringent regulatory expectations for indirect food contact applications when formulated and processed according to good manufacturing practices. Final compliance depends on the complete ink formulation, substrate, and intended migration conditions.
Q3: How should Duasyn Ink Blue SLK be dispersed in ink systems?
A: Optimal performance is achieved using high-shear dispersion techniques such as bead milling or high-speed dissolvers. Pre-wetting with compatible solvents or resins is recommended to ensure full deagglomeration and stable pigment distribution.
Q4: Does this pigment offer good lightfastness and heat stability?
A: Yes — Duasyn Ink Blue SLK delivers robust lightfastness and thermal stability suitable for standard ink drying and curing processes, including hot-air and IR drying. Performance under extreme processing conditions should be verified in the final formulation.
Q5: What is the typical dosage range in ink formulations?
A: Dosage varies depending on the desired shade intensity and ink system, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to total ink solids.
