Q1: What are the primary application areas for Permanent FBB 02 146?
A: Permanent FBB 02 146 is widely used in high-performance industrial coatings, automotive refinishes, and engineering plastics where excellent heat stability, lightfastness, and chemical resistance are required. It is also suitable for selected inks and specialty polymer applications demanding strong blue-shade red coloration.
Q2: How does this pigment perform under thermal processing conditions?
A: Permanent FBB 02 146 exhibits good thermal stability, making it suitable for melt-processing temperatures encountered in polyolefins, ABS, and other engineering thermoplastics. Performance remains robust up to typical extrusion and injection molding temperature ranges, though exact stability depends on residence time, matrix composition, and additive interactions.
Q3: Is this pigment compatible with common organic solvent-based and water-based systems?
A: Yes — Permanent FBB 02 146 demonstrates broad compatibility across solvent-borne industrial coating systems and aqueous dispersions. Its surface treatment supports stable dispersion in both polar and moderately non-polar media, though optimal dispersion typically requires appropriate wetting agents and high-shear mixing protocols.
Q4: What is the typical dosage range when formulating with this pigment?
A: Dosage depends on the target opacity, chroma, and substrate requirements, but Permanent FBB 02 146 is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in final formulations — due to its high tinting strength and efficient color development.
Q5: Does Clariant provide regulatory support or compliance documentation for this pigment?
A: Clariant offers comprehensive regulatory support, including REACH registration status, general food-contact suitability guidance (where applicable), and SDS documentation. Specific compliance assessments should be conducted in context of the final application, formulation matrix, and regional regulatory frameworks.
