Q1: What is the primary chemical classification and pigment type of Irgalite Red D3795 D4461?
A: Irgalite Red D3795 D4461 is a high-performance, azo-based organic pigment classified under Pigment Red 48:2 (PR48:2), offering strong tinting strength, good dispersibility, and balanced thermal stability for demanding industrial applications.
Q2: Is this pigment suitable for use in polyolefin plastics such as PP and PE?
A: Yes — D3795 D4461 is specifically engineered for excellent compatibility and dispersion in polyolefin systems, including injection-molded and extruded PP and PE, with good resistance to thermal degradation during processing.
Q3: How does its weathering and lightfastness performance compare to other PR48:2 pigments?
A: This grade delivers enhanced lightfastness and improved resistance to atmospheric exposure compared to standard PR48:2 variants, particularly when used in outdoor-oriented plastic applications — though long-term durability remains formulation- and substrate-dependent.
Q4: What are typical dosage ranges when using this pigment in plastic masterbatches?
A: Dosage typically ranges from 0.1% to 2% by weight in final plastic products, depending on desired shade depth, opacity requirements, and base resin characteristics — precise levels should be determined through lab-scale trials and process validation.
