Cathay FERROTINT Blue F28C Inorganic Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical composition of Cathay FERROTINT Blue F28C?

A: Cathay FERROTINT Blue F28C is a cobalt-free, iron-based inorganic blue pigment, formulated as a modified mixed metal oxide with iron and chromium as key constituents. Its color develops through controlled high-temperature calcination, yielding excellent thermal and chemical stability.

Q2: Is this pigment suitable for use in food-contact plastics or coatings?

A: While F28C complies with general safety requirements for inorganic pigments in non-intended food-contact applications, it is not pre-qualified for direct food-contact use under major regulatory frameworks. Customers must conduct full formulation-specific compliance testing—including extraction and migration assessments—prior to deployment in food-contact systems.

Q3: How does F28C perform under high-temperature processing conditions?

A: F28C exhibits outstanding thermal stability, retaining its blue hue and structural integrity up to approximately 900 °C in air. It is widely used in ceramic glazes, refractory coatings, and engineering thermoplastics processed at elevated temperatures without significant color shift or decomposition.

Q4: Can F28C be dispersed in aqueous systems without surface treatment?

A: Standard F28C has low inherent hydrophilicity and typically requires dispersion aids or surface modification for stable aqueous suspensions. For water-based inks, paints, or cementitious systems, we recommend using a specially treated grade or incorporating compatible dispersants during milling.

Q5: What are typical dosage ranges when using F28C in polymer masterbatches?

A: Dosage depends on the polymer matrix, required chroma, and processing method—but F28C is generally used at low concentrations due to its high tinting strength. Typical loading in polyolefin or polyester masterbatches ranges from 0.1% to 2% by weight, with optimization guided by trial compounding and colorimetric evaluation.
