Q1: What is the primary application field for Hostaperm Scarlet GO transp. pigment?
A: Hostaperm Scarlet GO transp. is primarily used in high-performance transparent or semi-transparent applications requiring strong chroma and excellent lightfastness — especially in automotive clearcoats, industrial coatings, and premium plastic coloration where transparency and thermal stability are critical.
Q2: Is this pigment suitable for use in polyolefins such as PP or PE?
A: Yes, Hostaperm Scarlet GO transp. demonstrates good compatibility and dispersion stability in polyolefins, including injection-molded and extruded PP and HDPE applications. Its particle size distribution and surface treatment support efficient incorporation during melt processing.
Q3: How does this pigment perform under elevated processing temperatures?
A: Hostaperm Scarlet GO transp. offers high thermal stability, maintaining color integrity during typical polymer processing conditions up to approximately 280 °C, making it suitable for engineering thermoplastics and demanding coating cure cycles.
Q4: What is the recommended dosage range for optimal color strength and transparency?
A: Dosage depends on the specific formulation and desired shade intensity, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — to achieve strong red tones while preserving transparency in clear systems.
