 Purpose
     Dodecenyl succinic anhydride/tetrapropylene succinic anhydride K12 (DDSA, TPSA) as epoxy curing agent can improve the water resistance and toughness of epoxy resin. Vantruth's high-purity dodecenyl succinic anhydride is widely used in the sealing and encapsulation of electronic components. As a cross-linking epoxy curing agent, it can improve the performance of products in many ways compared to other materials: improve Bond strength, increase toughness, improve electrical resistance and extend seal life.

In the application of corrosion inhibitors, alkenyl succinic anhydride and alkenyl succinic acid obtained by hydrolysis (including derivatives of both) are often used as corrosion inhibitors in water and hydrocarbon media. After adding dodecenyl succinic anhydride/tetrapropylene succinic anhydride K12 (DDSA, TPSA) into gasoline and diesel, the hydrolysis of the acid anhydride can absorb water, and the generated acid exists as a corrosion inhibitor. By adding a small amount of dodecenyl succinic anhydride to the mineral lubricating oil, it can prevent pitting corrosion and the formation of green scale for lead table copper bearings. At the same time, dodecenyl succinic anhydride can also improve the lubricity of the oil, increase the breakdown temperature, and reduce the friction system.
