Q1: What is the primary chemical class and pigment type of Hostaperm Red D3G 71?
A: Hostaperm Red D3G 71 is a high-performance perylene-based organic pigment, classified under the Pigment Red 179 (PR179) series. It exhibits excellent thermal stability and lightfastness, making it suitable for demanding polymer coloring applications.
Q2: In which polymer systems is this pigment most commonly used?
A: It is widely employed in engineering thermoplastics such as polyamide (PA), polybutylene terephthalate (PBT), and polyethylene terephthalate (PET), particularly where high-temperature processing and long-term color stability are required. It is also compatible with certain high-heat polyolefin compounds.
Q3: How does Hostaperm Red D3G 71 perform under high-shear and high-temperature compounding conditions?
A: This pigment demonstrates superior dispersion stability and resistance to thermal degradation during extrusion and injection molding, maintaining consistent hue and minimal color shift even at processing temperatures up to 300 °C in suitable polymer matrices.
Q4: Is Hostaperm Red D3G 71 suitable for food-contact or regulatory-sensitive applications?
A: While not inherently restricted, its suitability for food-contact applications depends on final formulation compliance and applicable regional regulations. Users must verify compatibility with relevant food-contact legislation through full system assessment and consultation with Clariant’s regulatory support team.
Q5: What is the typical dosage range when using this pigment in engineering plastics?
A: Dosage generally ranges from 0.1% to 2% by weight, depending on the desired shade intensity, polymer transparency requirements, and processing method. It is typically used at low concentrations due to its high tinctorial strength and excellent opacity.
