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 foams and also as an intermediate in the preparation of corrosion inhibitors for oils and greases. It cane be used 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.

- Storage
DDSA will react with water to form dodecenylsuccinic acid. This is normally undesirable, so DDSA should be stored in such a way that it is carefully protected from moisture contamination.

- Safety Precautions
Read and understand the relevant Material Safety Data Sheets (MSDS) for all products before use. These anhydrides are primary skin and eye irritants. Avoid contact with skin, eyes, and clothing. Use only with adequate ventilation. In case of contact, follow the procedures outlined in the MSDS. Generally, these procedures include immediately flushing the affected skin or eyes with copious amounts of water for at least 15 minutes. In the case of eye contact, get medical attention. Wash contaminated clothing before reuse.. Follow the recommendations in the MSDS for personal protective equipment when handling these materials. At a minimum, these procedures typically include protective chemical goggles, impenetrable gloves, and measures to avoid breathing chemical vapors.
