The powder form ensures precise dosing, consistent batch-to-batch reproducibility, and long-term stability when stored properly. Its molecular structure features sulfonic acid groups that facilitate strong ionic bonding with amino groups in fibers, resulting in vibrant, penetration-rich coloration with minimal bleeding.
Chromosal B
Chromosal B is a specialized chromium-based chemical reagent commonly used in analytical chemistry and laboratory applications. It is typically a chromium salt formulation that serves as a strong oxidizing agent, employed for various testing, purification, and synthesis processes. Chromosal B is valued for its high reactivity, stability in solution, and ability to facilitate oxidative reactions. It is widely used in industrial quality control, chemical synthesis, and wastewater treatment, offering reliable performance in oxidative degradation and metal treatment procedures.
Sulphur Black
Sulphur Black is a sulfur-based dye primarily used for dyeing cellulosic fibers such as cotton. It produces deep black shades with excellent fastness properties, including resistance to washing, light, and perspiration. Sulphur Black is widely utilized in the textile industry for producing durable, cost-effective black fabrics. The dyeing process involves reduction and oxidation steps to fix the color onto the fiber, making it ideal for bulk production.
