In the demanding world of polymer manufacturing, maintaining product clarity, color stability, and longevity is a constant challenge. Oxidation, residual monomers, and thermal processing can lead to unsightly yellowing and degradation, compromising the quality and value of the final product. At Sinocure Chemical Group, we have developed a cutting-edge solution designed to address these exact issues: Sinanox® HSA-2NA, a high-performance reducing and anti-yellowing agent.
Sinanox® HSA-2NA is a strategically engineered sulfonate derivative that functions as a dual-action protective agent. Its primary role is to effectively retard and inhibit yellowing in polymers, particularly within aqueous systems. It targets and neutralizes the root causes of discoloration—oxygen intrusion and residual reactive monomers like acrylic acid—ensuring your products maintain their intended color and aesthetic appeal from production through their entire service life.
Beyond its exceptional color-preserving capabilities, Sinanox® HSA-2NA enhances overall reaction activity. By facilitating more complete polymerization, it significantly reduces the content of unreacted monomers. This not only improves the polymer's performance profile but also contributes to a more stable and safer final material.
We understand that modern industry demands solutions that are both high-performing and responsible. Sinanox® HSA-2NA is formulated with this balance in mind:
Superior Thermal Stability: Withstanding temperatures up to 200°C, it remains effective even when added during the later stages of high-temperature drying processes, providing continuous protection against thermal-oxidative damage.
Inherently Eco-Safe Formula: The product is completely formaldehyde-free and does not generate formaldehyde during application. Its reaction by-products are simply benign salts and carbon dioxide, aligning with the strictest environmental and safety regulations.
Verified Green Compliance: Supporting your commitment to sustainability, Sinanox® HSA-2NA is developed with green principles. We provide supporting documentation for compliance and utilize antistatic packaging for enhanced safety and easier recycling.
Application Versatility: Its effectiveness is not limited to the production phase. Sinanox® HSA-2NA can be incorporated directly during synthesis or applied as a surface treatment solution to existing polymer products, offering flexibility in how you integrate protection into your processes.
Chemical Identity: Disodium hydroxyl(sulfonato)acetate (CAS No. 29736-24-1)
Appearance: White crystalline powder
Assay: ≥ 95.0%
Key Features: Excellent pH stability (6-8.5), low moisture content, and consistent particle size.
Sinanox® HSA-2NA is the ideal choice for formulators and manufacturers across a spectrum of applications where color integrity and polymer stability are paramount:
Aqueous Polymer Systems: Ideal for paints, coatings, adhesives, and textile binders.
Solid Polymer Processing: Protects engineering plastics and compounds during extrusion and molding.
Surface Treatments: Extends the life of finished goods like synthetic leather and plastic films.
Low-VOC Emulsions: A key ingredient for developing environmentally friendly next-generation materials.
In a market where product appearance and durability are directly linked to commercial success, Sinanox® HSA-2NA provides a reliable, advanced, and sustainable answer. It’s more than an additive; it’s an investment in the quality, longevity, and environmental profile of your polymer products.
