Sinanox® HSA-2NA

disodium hydroxy(sulfonato)acetate, blancolen HP alternative,SAP raw material,anti-yellowing agent

Sinanox® HSA-2NA is a sulfonate derivative primarily used as a high-performance reducing agent and anti-yellowing agent. It effectively retards and inhibits yellowing in polymers (especially in aqueous systems) caused by oxygen, residual monomers (e.g., acrylic acid), or thermal processing. It also enhances reaction activity and reduces monomer residues.

  • Versatile Application: Can be incorporated during production or applied as a solution to the surface of dried polymers to retard aging.

Application: :

Recommended for aqueous polymer dispersions or solid polymers in the following scenarios:

  • Aqueous Polymer Systems: Added during synthesis or drying to prevent thermal-oxidative yellowing.

  • Solid Polymer Processing: Functions as an antioxidant, providing protection at processing temperatures.

  • Surface Treatment: Its solution can be used to treat the surface of dried polymer products to slow aging.

  • Low-VOC Emulsion Synthesis: Suitable for environmentally friendly emulsion preparation due to its formaldehyde-free nature.
