Description

Glutaraldehyde Sodium Bisulfite Addition Compound, 95% is a stabilized, water-soluble derivative of glutaraldehyde, formed by the addition of sodium bisulfite. This compound is valued for its controlled reactivity and enhanced handling safety compared to free glutaraldehyde, serving as a versatile intermediate and cross-linking agent. It is essential for manufacturers in the leather tanning, textile processing, and specialty polymer industries seeking reliable, high-purity chemical building blocks.

Application

• Leather Tanning Agent: Used as a high-performance cross-linking agent for collagen fibers, improving leather's hydrothermal stability, softness, and dye uptake.
• Textile Finishing: Acts as a durable press resin and cross-linker for cellulose-based fabrics, enhancing wrinkle resistance and dimensional stability.
• Biocide Intermediate: Serves as a precursor in the synthesis of stabilized glutaraldehyde-based disinfectants and preservatives for industrial water systems.
• Polymer Modification: Employed as a cross-linking agent for polyvinyl alcohol (PVA) and other hydroxyl-containing polymers to produce films, adhesives, and hydrogels.
• Paper Wet-Strength Resin: Functions as a co-reactant to improve the wet strength and dry strength of specialty paper grades.
• Protein Fixation: Used in histological and diagnostic reagent formulations for the gentle fixation of biological tissues and proteins.
