Q1: What is the primary chemical class of Hostaperm Red Violet ER 02?
A: Hostaperm Red Violet ER 02 is a high-performance quinacridone-based organic pigment, offering excellent lightfastness, weather resistance, and thermal stability typical of this pigment family.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Hostaperm Red Violet ER 02 is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial plastics, coatings, and specialty inks where high chroma and durability are required.
Q3: How does its dispersion behavior compare in PVC versus polyolefins?
A: The pigment exhibits good dispersibility in rigid and flexible PVC formulations due to its optimized surface treatment. In polyolefins, it requires robust dispersion protocols—such as high-shear compounding or masterbatch dilution—to achieve optimal color development and stability.
Q4: Can it be used in water-based systems?
A: While primarily designed for solvent-based and melt-processing applications, Hostaperm Red Violet ER 02 can be formulated into aqueous dispersions using appropriate surfactants and stabilization techniques—though performance may vary depending on pH, ionic strength, and binder compatibility.
Q5: What is the recommended dosage range for achieving full opacity in standard plastic applications?
A: Dosage depends on the substrate, desired shade depth, and processing conditions, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve strong tinting strength and good opacity in most thermoplastics.
