Trimellitic Anhydride

Trimellitic Anhydride (TMA)

 

TECHNOLOGY FOR THE PRODUCTION OF TRIMELLITIC ANHYDRIDE (TMA)

 

Trimellitic Anhydride (1,3–Dihydro-1,3 Dioxo–5–Iso-benzofurancarboxylic acid, TMA) is a very reactive chemical of relatively low molecular mass.
Many of its industrial uses depend on the reactivity of the anhydride group.
It is mainly used in the synthesis of trimellitate esters, used as plasticizers of PVC and other various synthetic resins, especially when temperature and water stability are required.

Other TMA applications include:

  • - Adhesives
  • - Solvent-borne and waterborne coatings
  • - Powder coatings
  • - Binder for aggregates
  • - Curing agent for epoxy and other resins
  • - Paints
