DDSA

Dixie dodecenylsuccinic anhydride (DDSA) is a slightly viscous liquid anhydride. DDSA can be used as: An epoxy curing agent for electrical potting compounds, coatings, conductive adhesives, and syntactic foam; An intermediate in the preparation of corrosion inhibitors for oils and greases; As a leather tanning agent. When used as an epoxy-curing agent, it has a long pot life at room temperature and gives excellent electrical properties and flexibility to castings. DDSA can be used in blends with other anhydrides to modify physical properties of the mixture and to lend flexibility and reduce brittleness of cured polymers.
