Q1: What is the primary chemical class of Hostaperm Scarlet GO?
A: Hostaperm Scarlet GO is a high-performance perylene-based organic pigment, offering excellent heat stability, lightfastness, and migration resistance in demanding polymer applications.
Q2: Is this pigment suitable for food-contact plastics?
A: Hostaperm Scarlet GO is designed for use in plastics intended for indirect food contact, subject to compliance with applicable regional regulatory frameworks and final formulation assessment by the compounder or converter.
Q3: Which polymers show optimal dispersion and color strength with this pigment?
A: It delivers outstanding performance in polyolefins (PP, PE), engineering thermoplastics (e.g., PA, PBT), and PVC, particularly where high thermal stability during processing is required.
Q4: How does Hostaperm Scarlet GO compare to conventional quinacridone reds in terms of weathering resistance?
A: Due to its perylene backbone, Hostaperm Scarlet GO provides superior long-term outdoor durability and UV resistance compared to many quinacridone-based alternatives, especially in unpigmented or lightly stabilized systems.
Q5: What is the typical dosage range in polymer masterbatches?
A: Dosage generally ranges from 0.1% to 2% by weight depending on the target shade depth, polymer matrix, and processing conditions—typical usage is at low concentrations to achieve strong tinting strength and cost efficiency.
