Trimellitic Anhydride

Trimellitic Anhydride, also known as Trimellitic Anhydride or 1,3-dioxo-2-benzofuran-5-carboxylic acid, is an organic compound with the molecular formula C9H4O5. This white crystalline powder represents trimellitic acid anhydride. Trimellitic Anhydride is known for its industrial applications, but also for the risks associated with its exposure.

Trimellitic Anhydride is primarily used to manufacture many industrial products including coatings, adhesives and plastics. Its use is also often in the production of specialty resins, which are mainly used in the electronics industry, for example in insulation for electric motors or transformers. In addition, it is also used in the automotive industry, specifically in the production of antifreeze. Because of its chemical properties, it is able to raise the boiling point and at the same time lower the freezing point of a mixture of water and coolant. It is also used to produce plasticizers that increase the flexibility, strength, durability and resistance of PVC products. The last major area is the production of polyester and alkyd resins, which are used in the mass production of coatings.
