Q1: What is the primary chemical composition of Cathay FERROTINT Red F3300?
A: Cathay FERROTINT Red F3300 is an iron oxide-based inorganic pigment, primarily composed of hematite (α-Fe₂O₃), engineered for high chroma, thermal stability, and consistent particle morphology.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Cathay FERROTINT Red F3300 is designed for general industrial applications and is not pre-qualified for direct food-contact use. Customers requiring compliance with food safety regulations must conduct full formulation-level testing and verification per applicable regional requirements.
Q3: How does this pigment perform under high-temperature processing conditions?
A: As a thermally stable iron oxide pigment, Cathay FERROTINT Red F3300 maintains its color integrity and structural stability during typical polymer processing—including injection molding and extrusion—at temperatures up to approximately 350°C, depending on residence time and atmosphere.
Q4: Can it be dispersed effectively in both aqueous and solvent-based systems?
A: Yes—Cathay FERROTINT Red F3300 exhibits good dispersibility in a broad range of media, including water-based emulsions, alkyd resins, polyurethanes, and PVC plastisols, though optimal dispersion typically requires appropriate surfactants or dispersing aids tailored to the system.
Q5: What are the recommended handling precautions for this pigment?
A: Standard industrial hygiene practices apply: avoid inhalation of dust, use local exhaust ventilation during dry handling, and wear appropriate PPE such as N95 respirators and gloves. The material is non-toxic but should be treated as a fine particulate to minimize respiratory exposure.
