Q1: What is the primary chemical class of Hostaperm Red D3G 70?
A: Hostaperm Red D3G 70 is a high-performance perylene-based organic pigment, known for its excellent thermal stability, lightfastness, and resistance to migration in demanding polymer applications.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Hostaperm Red D3G 70 is not pre-approved for direct food-contact applications under major global regulatory frameworks. Its suitability must be evaluated case-by-case based on the final formulation, processing conditions, and applicable regional regulations — consultation with Clariant’s regulatory team is recommended prior to use.
Q3: How does Hostaperm Red D3G 70 perform in high-temperature polymer processing?
A: This pigment exhibits strong thermal stability and is widely used in engineering thermoplastics such as polyesters, polyamides, and polycarbonates processed at elevated temperatures. It maintains color integrity and shows minimal degradation or blooming under standard melt-processing conditions.
Q4: What is the typical dosage range when incorporating this pigment into plastic compounds?
A: Dosage depends on the desired shade strength and substrate, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in most polymer systems—to achieve optimal color development and dispersion without compromising physical properties.
Q5: Can Hostaperm Red D3G 70 be used in solvent-based coatings or inks?
A: While primarily developed and optimized for polymer coloring, this pigment can be formulated into certain high-solids solvent-based coating systems—though its performance in liquid media depends heavily on proper surface treatment, dispersant selection, and stabilization strategy.
