Amino Diphenyl Sulfone

Amino Diphenyl Sulfone (DDS / Dapsone) is a high-performance chemical compound widely recognized for its excellent thermal stability and chemical resistance. Appearing as a white to off-white crystalline powder, this diamine-based material contains two amino groups attached to a diphenyl sulfone backbone, which enhances its reactivity and durability. Due to these unique properties, DDS is commonly used as a curing agent in epoxy resin systems, delivering superior mechanical strength, heat resistance, and long-lasting performance in industrial applications.
