Q1: What is the primary chemical class and hue characteristic of K8730 G?
A: BASF K8730 G is a high-performance perylene-based organic pigment, offering a clean, bluish-red shade with excellent chroma and strong tinting strength. It belongs to the Heliogen® family, engineered for superior lightfastness and thermal stability in demanding applications.
Q2: Is K8730 G suitable for use in automotive coatings or plastic coloration?
A: Yes — K8730 G is widely used in engineering plastics (e.g., polyolefins, polyesters) and high-end automotive topcoats due to its outstanding resistance to heat, light, and weathering. Its dispersion stability supports consistent color development across extrusion and injection molding processes.
Q3: How should K8730 G be dispersed for optimal performance?
A: Optimal dispersion requires high-shear processing — such as bead milling or three-roll grinding — in compatible resin systems. Pre-dispersed pastes or masterbatches are recommended for reproducible results, especially in sensitive applications like thin-film coatings or transparent plastics.
Q4: Does K8730 G contain heavy metals or halogens?
A: No — K8730 G is a halogen-free, heavy-metal-free organic pigment, compliant with global regulatory expectations for sustainable pigmentation, including RoHS and REACH requirements for restricted substances.
Q5: What is the typical dosage range when using K8730 G in polymer systems?
A: Dosage depends on formulation requirements and desired opacity or transparency, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — due to its high tinctorial strength and efficient color development.
