Q1: What is the primary application field for GRAPHTOL F5RK 170?
A: GRAPHTOL F5RK 170 is specifically developed for high-performance gravure and flexographic inks used in packaging applications, particularly where excellent rub resistance, gloss, and pigment strength are required.
Q2: Is GRAPHTOL F5RK 170 suitable for food-contact packaging inks?
A: Yes — GRAPHTOL F5RK 170 is designed to meet regulatory expectations for non-migrating organic pigments in food packaging inks, provided it is formulated and processed in accordance with applicable good manufacturing practices and end-use compliance requirements.
Q3: How does GRAPHTOL F5RK 170 compare to conventional phthalocyanine blue pigments in terms of dispersion stability?
A: GRAPHTOL F5RK 170 offers enhanced dispersion stability in polar solvent-based and water-reducible ink systems due to its optimized surface treatment, resulting in reduced flocculation tendency and improved long-term storage performance.
Q4: What types of resin systems is GRAPHTOL F5RK 170 typically compatible with?
A: It demonstrates broad compatibility with common ink resins including nitrocellulose, acrylics, polyamides, and maleic rosin derivatives, especially in low-viscosity gravure formulations.
Q5: What is the typical dosage range for GRAPHTOL F5RK 170 in ink formulations?
A: Dosage depends on formulation requirements and desired shade intensity, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to total ink solids.
