Q1: What is the primary chemical composition of Ferro PS 24-3095 PK?
A: Ferro PS 24-3095 PK is a mixed-metal oxide pigment based on iron and chromium, formulated to deliver stable, heat-resistant black coloration in high-performance inorganic pigment applications.
Q2: Is this pigment suitable for use in food-contact plastics or coatings?
A: Ferro PS 24-3095 PK is designed for industrial and decorative applications where regulatory compliance with food-contact standards is not required. It is not certified for direct food-contact use; customers requiring such compliance should consult Ferro’s dedicated food-safe pigment portfolio.
Q3: How does Ferro PS 24-3095 PK perform under high-temperature processing conditions?
A: This pigment exhibits excellent thermal stability and retains its color integrity during standard polymer processing, including injection molding and extrusion at temperatures up to approximately 300 °C. Its inorganic nature ensures minimal decomposition or color shift in thermoplastics and thermosets.
Q4: What types of resins or binders is Ferro PS 24-3095 PK typically compatible with?
A: The pigment demonstrates broad compatibility with common engineering and commodity polymers—including polyolefins, polyesters, polyamides, and epoxy systems—as well as ceramic glazes and inorganic coatings. Dispersion behavior may vary depending on resin polarity and processing method, so preliminary compatibility testing is recommended.
Q5: What is the typical dosage range when using this pigment in plastic coloration?
A: Dosage depends on the desired opacity, color strength, and base resin, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—to achieve consistent black shades without compromising mechanical properties.
