Q1: What is the primary application of Holliday Ultramarine Blue HG?
A: Holliday Ultramarine Blue HG is a high-purity, heat-stable inorganic pigment primarily used for coloration in thermoplastic and thermoset polymers, architectural coatings, and specialty inks where excellent lightfastness and chemical resistance are required.
Q2: Is Holliday Ultramarine Blue HG suitable for food-contact applications?
A: Holliday Ultramarine Blue HG is not intended for direct food-contact applications. It does not meet regulatory requirements for pigments used in food packaging or food-processing equipment unless specifically validated and approved by the end-user’s regulatory team under applicable local frameworks.
Q3: How does Holliday Ultramarine Blue HG perform under elevated processing temperatures?
A: This grade exhibits enhanced thermal stability compared to standard ultramarine blues and retains its characteristic blue hue up to approximately 200 °C in short-term processing conditions, making it suitable for many extrusion and injection molding operations.
Q4: Can Holliday Ultramarine Blue HG be used in acidic systems?
A: No — like all ultramarine pigments, Holliday Ultramarine Blue HG is sensitive to acidic environments and may undergo color degradation or fading below pH ~5.5. It is best suited for neutral to alkaline formulations.
Q5: What is the typical dosage range for optimal color development?
A: Dosage depends on the base system and desired intensity, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — with good dispersion being critical to achieving uniform color and maximizing tinting strength.
