For professionals in the chemical and manufacturing industries, understanding the precise specifications of raw materials is fundamental to achieving optimal product performance and cost-effectiveness. Solvent Red 8, identified by CAS number 33270-70-1, is a widely used red pigment whose quality directly impacts the final product. This article provides key specifications and insights for B2B buyers interested in purchasing this essential industrial colorant from China.

The appearance of high-quality Solvent Red 8 is a bright red powder, ensuring ease of dispersion and integration into various media. Crucially, its dyeing strength is typically rated between 98-102%, indicating a high concentration of the coloring agent and excellent tinting capability. This means manufacturers can achieve intense and consistent red hues even with moderate usage, leading to economic benefits. When purchasing, always confirm the dyeing strength to ensure optimal performance in your application.

Beyond strength, resistance properties are vital for longevity and durability. Solvent Red 8 exhibits good to very good light fastness, generally rated 4-5 on the blue wool scale. This ensures that colors remain vibrant and do not fade significantly upon exposure to light. Its heat resistance, typically around 140°C, is sufficient for many plastic processing applications. Furthermore, its stability against acid and alkali further broadens its applicability in challenging chemical environments. These resistance characteristics are key selling points for industrial users.

The pH value of Solvent Red 8 typically falls between 6.0-8.0, indicating a neutral formulation that is compatible with a wide range of other additives and substrates. Moisture content is usually kept below 2.0% max, and insolubles in solvents like MEK are maintained below 1.0% max, ensuring ease of handling and preventing issues like clogging or uneven coloration. These parameters are critical for formulators aiming for smooth production processes.
