Beschreibung

Allgemeine Beschreibung

Non-hygroscopic, forms urethanes with good hydrolytic stability, dry heat aging and chemical and environmental resistance.

1,3-Propanediol bis(4-aminobenzoate) (PBA) is an aromatic diamine. Its crystal structure has been determined by single crystal X-ray diffraction. Its ability to improve the flexibility of electrically conductive adhesives (ECAs) has been studied. Results show that it has a good impact on the electrical, mechanical and thermal properties of the ECAs.

Anwendung

A safe, high performance reactant with polyurethane and epoxide prepolymers.

1,3-Propanediol bis(4-aminobenzoate) (PBA) may be used as a flexibilizer, to prepare a flexible epoxy molding compound (EMC) and also as a chain extender in the synthesis of degradable poly(esterurethane urea) (PEUUR).
