Q1: What is the primary chemical composition of Cathay FLOWTINT Red FF3330?
A: Cathay FLOWTINT Red FF3330 is an iron oxide-based inorganic pigment, formulated as a modified hematite (α-Fe₂O₃) with surface treatment to enhance dispersibility and thermal stability in polymer and coating systems.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Yes — FF3330 is manufactured under strict quality control to meet general requirements for pigments used in food-contact applications, subject to final formulation compliance and regulatory review by the end-user’s technical and regulatory teams.
Q3: How does FF3330 perform under high-temperature processing conditions?
A: This pigment exhibits excellent thermal stability, retaining its color integrity and structural integrity during typical polymer processing operations such as extrusion, injection molding, and calendering up to 280 °C.
Q4: What types of resins or binders is FF3330 most commonly used with?
A: FF3330 demonstrates broad compatibility with thermoplastics (e.g., PP, PE, PS), thermosets (e.g., epoxy, unsaturated polyester), and water- or solvent-based architectural and industrial coatings.
Q5: What is the recommended approach for achieving optimal dispersion in masterbatch production?
A: For best results, incorporate FF3330 using high-shear mixing equipment during masterbatch preparation; pre-wetting with compatible carrier resin or dispersant is advised to minimize agglomeration and ensure uniform color development.
