Q1: What is the primary chemical composition of Cathay FERROTINT Green F18Y?
A: Cathay FERROTINT Green F18Y is a complex inorganic mixed metal oxide pigment, based predominantly on iron and chromium oxides, engineered to deliver stable green coloration with high thermal and chemical resistance.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Cathay FERROTINT Green F18Y is formulated for industrial applications where regulatory compliance with food-contact standards is not required. It is not pre-qualified for direct food-contact use; customers must conduct full regulatory assessment—including migration testing—based on their specific end-use and applicable jurisdictional requirements.
Q3: How does F18Y perform under high-temperature processing conditions?
A: As an inorganic oxide pigment, F18Y exhibits excellent thermal stability and retains its color integrity during standard polymer processing—including injection molding, extrusion, and calendering—at temperatures up to approximately 800°C in inert atmospheres. In typical polymer melts (e.g., polyolefins, engineering thermoplastics), it remains stable well beyond common processing ranges.
Q4: Can F18Y be dispersed effectively in water-based systems?
A: While inherently hydrophobic due to its inorganic oxide nature, F18Y can be successfully incorporated into aqueous systems using appropriate dispersants, surfactants, or surface treatments. Optimal dispersion typically requires high-shear mixing and formulation-specific stabilization strategies.
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, gloves, and safety goggles. The material is non-volatile and non-flammable, but good housekeeping minimizes airborne particulate exposure.
