Application: | Tetrafunctional epoxy resins can be blended with DDS and can be thermally cured which can be used in oil field applications. DDS can also be used to cure iron oxide (Fe2O3) layer double hydroxide based epoxy that forms a flame retardant epoxy nanocomposites. It can also be used as a hardener to cure bisphenol A (DGEBA) for use in the fabrication of flame retardant epoxy/clay nanocomposites. |
General description: | 4-aminophenyl sulfone (DDS) is a diamine-based hardener that is used to cure epoxy-based resins. |
