At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on offering high-performance chemical solutions, and Solvent Red 8 is a prime example. With the CAS number 33270-70-1, this metal complex solvent dye is valued not just for its vibrant red color but also for its robust chemical and physical properties that translate into significant advantages for end-users. Understanding these characteristics is key to appreciating its wide-ranging utility.

The chemical structure of Solvent Red 8, often described as a chromium complex of an azo dye, endows it with exceptional stability. This stability manifests in several ways, including good lightfastness, meaning the color resists fading when exposed to sunlight, and excellent thermal stability, allowing it to withstand elevated temperatures during processing without degrading. These properties are crucial for applications where product longevity and color retention are paramount. For instance, manufacturers of automotive coatings or high-temperature plastics rely heavily on the reliable performance of such dyes.

Solvent Red 8's miscibility and solubility in a broad spectrum of organic solvents are among its most significant advantages. Whether it’s alcohols, ketones, esters, or aromatic hydrocarbons, the dye readily dissolves, ensuring uniform distribution and preventing issues like pigment aggregation or uneven coloration. This characteristic is vital for achieving smooth finishes in applications like solvent-based inks and coatings. If you are sourcing Solvent Red 8 for inks, this solubility is a critical factor.

Another key advantage is its compatibility with various synthetic and natural resins. This ensures that the dye can be effectively integrated into diverse polymer matrices and coating systems without causing adverse reactions or compromising the integrity of the base material. This broad compatibility makes Solvent Red 8 a versatile choice for formulators working with different substrates.

The acid and alkali resistance of Solvent Red 8 further adds to its appeal. This means the dye can maintain its color integrity in environments or during processes where exposure to acidic or alkaline conditions is unavoidable. This resilience is particularly valuable in industrial settings where products might encounter cleaning agents or harsh environmental factors.

For businesses looking to purchase Solvent Red 8, NINGBO INNO PHARMCHEM CO.,LTD. offers a reliable source for this high-quality dye. Their commitment to rigorous quality control ensures that each batch meets the specified technical data, providing customers with confidence in their raw material supply. The competitive price of Solvent Red 8, when considering its performance, makes it an economically viable option for many industrial applications.
