For professionals in the chemical and manufacturing industries, a deep understanding of pigment properties is crucial for successful product formulation and quality control. Pigment Red 48:2 (CAS 7023-61-2), a monoazo calcium salt, presents a compelling profile of chemical and physical characteristics that make it a valuable asset in diverse industrial applications. As a dedicated manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. prioritizes transparency regarding the technical specifications of the materials we provide.

Chemically, Pigment Red 48:2 belongs to the monoazo pigment class, specifically a calcium salt derivative. Its molecular formula, C18H15CaClN2O6S, and molecular weight of approximately 462.91 g/mol, provide the fundamental composition. The pigment’s structure contributes to its distinct bluish-red hue and its insolubility in water and common organic solvents, a key attribute for its use in non-aqueous systems like inks and plastics.

Physically, Pigment Red 48:2 is typically supplied as a fine red powder. Its specific gravity usually ranges between 1.60 and 1.71 g/cm³, and its bulk volume is generally around 2.2-2.6 L/kg. These properties are important for calculating loading levels and understanding the pigment's behavior during dispersion and processing. The typical oil absorption rate, often around 45-55 ml/100g, influences the amount of binder or vehicle required to achieve optimal dispersion and flow.

Key performance metrics are where Pigment Red 48:2 truly shines for industrial applications. Its lightfastness is generally rated at 5-6 on a scale of 8, indicating good resistance to fading under light exposure. Heat resistance is another critical factor, with many sources indicating stability up to 180°C or even 220°C, making it suitable for plastics processing and oven-cured coatings. Furthermore, its acid and alkali resistance (typically rated 4-5) and oil resistance (rated 4-5) ensure color stability in various chemical environments.

For companies looking to buy Pigment Red 48:2, these technical specifications translate directly into product reliability. Whether you are a formulator of printing inks, a compounder of plastics, or a producer of paints and coatings, understanding these parameters allows for precise application and predictable results. As a reputable Chinese manufacturer, we ensure our Pigment Red 48:2 meets these specifications consistently, offering a dependable source for your manufacturing needs. We encourage clients to consult our detailed Technical Data Sheets (TDS) and Material Safety Data Sheets (MSDS) for comprehensive information, and to purchase with confidence.
