| Hexahydrophthalic anhydride Usage And Synthesis |
| Description | Hexahydrophthalic anhydride (HHPA) is widely used for electronics applications, e.g. HHPA cured epoxy resins have excellent dielectric properties, high-temperature stability, and high glass transition temperatures. HHPA is used as a curing agent in adhesive coatings and sealant materials, e.g. for the second-generation two-part epoxy adhesive synthesis. Hexahydrophthalic anhydride is also used in the manufacture of alkyd and polyester resins, insecticides, and rust preventives. |

| Chemical Properties | White crystalline powder |
| Uses | Intermediate for alkyds, plasticizers, insect repellents, and rust inhibitors; hardener in epoxy resins. |
| Uses | HPPA, in combination with triethaylamine (TEA), can be used as a polymerization initiator in the preparation of polyester based resins. It can also be used as a hardener to cure 1,4-butanediol diglycidyl ether which can be used as an epoxy based system for electronic devices. |
| Application | Predominantly cis 1,2-cyclohexanedicarboxylic anhydride (HHPA) is a cyclic anhydride that can be used for a variety of applications such as: plasticizer, rust inhibitor, and a curing agent for epoxy based resins.
