Q1: What is the primary chemical composition of Cathay FERROTINT Orange F6700?
A: Cathay FERROTINT Orange F6700 is a high-performance inorganic pigment based on complex iron oxide–zinc oxide mixed-phase chemistry, engineered for enhanced thermal stability and lightfastness. It does not contain heavy metals such as lead, cadmium, or chromium(VI).
Q2: Is this pigment suitable for use in food-contact plastics?
A: Yes, Cathay FERROTINT Orange F6700 is formulated to meet general requirements for pigments used in food-contact polymer applications, provided it is incorporated within approved polymer matrices and processing conditions. Final compliance depends on full system evaluation per applicable regional regulations.
Q3: How does F6700 perform under high-temperature processing, such as injection molding or extrusion?
A: This pigment demonstrates excellent thermal stability, retaining its orange hue and dispersion integrity at typical polymer processing temperatures up to 280 °C. It is especially suited for polyolefins, engineering thermoplastics, and masterbatch applications requiring robust heat resistance.
Q4: Can F6700 be used in aqueous systems like architectural coatings or water-based inks?
A: While primarily optimized for polymer coloration, F6700 can be adapted for aqueous dispersions with appropriate surface treatment and stabilization. Performance in water-based systems may require formulation support to ensure optimal rheology, gloss retention, and sedimentation resistance.
