Product description

IUPAC: 1,4-benzenedecarboxylic acid

Eastman™ Purified Terephthalic Acid (PTA) is used to manufacture polyester coatings resins for use in the formulation of general metal, appliance, automotive, industrial maintenance, and coil coatings. The primary application for PTA is in combination with Eastman NPG™ Glycol in polyester powder coating resins. It has also been used in unsaturated polyesters for fiberglass-reinforced plastics applications.

The aromatic ring of PTA imparts excellent hardness and corrosion and stain resistance to coatings resins and unsaturated polyesters. PTA has moderate solubility in molten glycols which can increase synthesis times, and it imparts moderate solubility to resins.

Eastman™ PTA is only available in the United States in bulk quantities.
