Application Scenarios
Electroplating & Surface Treatment – Widely used for tin plating and copper-tin alloy plating of mechanical parts. It acts as a sensitizer for ABS plastic electroplating, effectively enhancing coating adhesion and avoiding peeling defects.
Textile & Fine Chemical Industry – Functions as a dyeing mordant and discharge printing resisting agent in textiles. It also serves as a reducing bleacher and key intermediate for dye synthesis, plus a functional additive for ultra-high-pressure lubricants and mirror silvering sensitization.
Advanced & Food-Grade Usage – Applied as an organic reaction catalyst and butyl rubber vulcanization activator. With qualified food-grade purity, it acts as a safe antioxidant and stabilizer for fruit juice and canned food preservation, also applicable in pharmaceutical synthesis and fragrance formulation.
