Usage
Phosphorus-containing flame-retardant chain extender for polyurethanes: Used in high-end polyurethane foams, leather pastes, waterproof adhesives, and electronic potting compounds to enhance heat and tear resistance.
Curing agent for leather and adhesives: A cross-linking and curing monomer for high-grade synthetic leather, polyurethane sealants, and industrial structural adhesives; improves bond strength, aging resistance, and flame retardancy.
Fine chemical intermediate: Used in the synthesis of dyes, agricultural fungicides, and active pharmaceutical intermediates; the aromatic amino group enables diazotization and condensation reactions for the production of functional chemicals containing sulfur-phosphorus heterocycles.
Functional additive for epoxy resins and coatings: Low-temperature curing accelerator for epoxy systems; functional filler for flame-retardant, anti-corrosion coatings, improving weather resistance, fire resistance, and rust protection.
