For industries requiring robust and reliable coloration solutions, understanding the specific properties of a dye is essential. Solvent Blue 104, known by its CAS number 116-75-6, is a highly regarded anthraquinone-based dye that offers a compelling set of characteristics for diverse industrial applications. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer in China, provides this key colorant.

At its core, Solvent Blue 104 is celebrated for its vibrant blue hue and exceptional performance metrics. Chemically identified as 1,4-bis(mesitylamino)anthraquinone, it possesses a molecular formula of C32H30N2O2 and a molecular weight of 474.59 g/mol. These structural elements contribute to its outstanding heat resistance, often cited as stable up to 300°C in certain plastic matrices like PS and ABS. This high thermal stability is a critical factor for processes involving elevated temperatures, ensuring color integrity.

Lightfastness is another significant attribute of Solvent Blue 104, typically rated between 7 and 8 on the blue wool scale. This indicates superior resistance to fading upon exposure to light, making it suitable for applications where long-term color durability is required, such as in automotive parts or exterior architectural elements. When you buy Solvent Blue 104, you are investing in color that lasts.

Its solubility profile is also noteworthy; it is readily soluble in many organic solvents, including chloroform and acetone, which facilitates its incorporation into various industrial formulations, including inks, paints, coatings, plastics, lubricants, and fuels. While its water solubility is very low (typically less than 1%), its efficacy in non-aqueous systems is high.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-purity Solvent Blue 104. For businesses looking to purchase this versatile dye, understanding these key properties helps in selecting the optimal colorant for their specific industrial dyeing needs. Our position as a manufacturer in China ensures that you receive a product that meets stringent quality controls for consistent performance.
