Q1: What is the primary chemical composition of Cathay FERROTINT Orange F6200?
A: Cathay FERROTINT Orange F6200 is an iron oxide-based inorganic pigment, primarily composed of alpha-iron oxide (α-Fe₂O₃) with controlled crystallinity and particle morphology to deliver consistent orange hue and high thermal stability.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Cathay FERROTINT Orange F6200 is not pre-certified for direct food-contact applications. It may be considered for indirect food-contact uses where regulatory compliance is verified by the end-formulator — always confirm suitability against applicable regional requirements and perform required migration testing.
Q3: How does F6200 compare to organic orange pigments in terms of heat stability?
A: As an inorganic iron oxide pigment, F6200 offers significantly higher thermal stability than most organic orange pigments — it remains stable during standard polymer processing (e.g., extrusion, injection molding) and retains color integrity at temperatures exceeding 300 °C.
Q4: Can F6200 be dispersed in water-based systems without surface treatment?
A: While F6200 is inherently hydrophilic due to its iron oxide nature, optimal dispersion in water-based paints or inks typically benefits from compatible dispersants or mild pH adjustment — untreated addition may lead to reduced stability or sedimentation over time.
Q5: What is the typical dosage range when using F6200 in architectural coatings?
A: Dosage depends on desired opacity and shade intensity, but F6200 is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to total formulation — to achieve strong chromatic performance while maintaining cost efficiency and rheological balance.
