Q1: What is the primary application field for Graphtol Bordeaux HF3R?
A: Graphtol Bordeaux HF3R is specifically developed for high-performance gravure and flexographic inks used in packaging applications, particularly where excellent gloss, strong tinting strength, and good print definition are required on films and coated papers.
Q2: Is this pigment suitable for food-contact packaging inks?
A: Graphtol Bordeaux HF3R is designed to meet stringent regulatory expectations for packaging inks intended for indirect food contact. It complies with major global ink safety guidelines when formulated and processed according to Clariant’s recommended practices and end-use conditions.
Q3: How does HF3R differ from other Bordeaux-shade pigments in the Graphtol series?
A: HF3R offers enhanced heat stability and improved dispersibility in low-viscosity, fast-drying solvent-based ink systems compared to standard Bordeaux grades—making it especially suited for high-speed gravure printing on heat-sensitive substrates.
Q4: What solvents or resin systems is Graphtol Bordeaux HF3R typically compatible with?
A: It demonstrates good compatibility with common nitrocellulose, polyamide, and acrylic-based ink vehicles, as well as a range of aromatic and aliphatic hydrocarbon solvents and ester blends commonly used in flexible packaging inks.
Q5: What is the typical dosage range in ink formulations?
A: Dosage depends on the desired shade intensity and substrate, but Graphtol Bordeaux HF3R is generally used at low concentrations—typically ranging from 0.1% to 2% by weight in finished ink systems—to achieve optimal color performance and rheological behavior.
