Overview

4-Aminobenzenesulfone (DDS) is a diamine curing agent used for curing epoxy resins.

Product application:

Product application: Tetrafunctional epoxy resin can be mixed with DDS and can be heat cured for oilfield applications. DDS can also be used to cure layered double hydroxide based epoxy resins of iron oxide (Fe2O3), forming flame-retardant epoxy resin nanocomposites. It can also be used as a curing agent to cure bisphenol A (DGEBA) used in the manufacture of flame-retardant epoxy resin/clay nanocomposites.
