Description
1,2,4-Benzenetricarboxylic anhydride is used to produce good heat-proof, weather-proof and solvent-proof trimellitate plasticizers, to synthesize polyester resins, curing agent of epoxy resins, heat-proof insulated laminas, heat-proof varnishes, stabilizers, dyestuffs, pigments, surfactants. TMA can also be used as accelerant for vulcanization, treating agent of fiber and flocculant of film. It has wide application to high class aerooil, impregnating oil for power capacitors, adhesives for granules, instant adhesives, sizing agents, antismoke agents, dyestuffs, printing inks, medicines and farm chemicals.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
