Diglycidyl terephthalate

Diglycidyl terephthalate (CAS 7195-44-0), also known as terephthalic acid diglycidyl ester, is a bifunctional epoxy monomer used as a reactive building block and crosslinker in polymer systems.

Its two epoxide groups enable controlled network formation in thermoset formulations, making it a functional component in coatings, adhesives, and specialty resin development for industrial use.

In powder coatings, it functions as a crosslinking agent for carboxyl-functional polyester resins, contributing to film hardness and chemical resistance in various industrial finish systems.

Adhesive and sealant formulators incorporate it to build epoxy networks with defined aromatic backbone rigidity, relevant where thermal and mechanical performance are specified for the end product.

In polymer research and specialty resin manufacturing, it serves as a monomer for synthesizing epoxy-polyester copolymers with tailored Tg and crosslink density for specific applications.

It is also evaluated as a reactive diluent or modifier in structural adhesive systems where aromatic character improves thermal stability and overall durability of the bonded materials.

Diglycidyl terephthalate is supplied as a solid, typically a white to off-white crystalline powder or flake. It is available primarily in technical grade for industrial and research applications.

Packaging ranges from small quantities for laboratory and formulation development to bulk quantities for manufacturing use, ensuring flexibility for both small-scale and large-scale operations.
