ABSTRACT

Fundamental studies aimed at elucidating the
key contributions to corrosion performance are needed to make progress toward
effective and environmentally compliant corrosion control. Epoxy/amine systems
are typically employed as barrier coatings for corrosion control. However, the
hardening agents used for coating applications can be very complex, making
fundamental studies of water and oxygen permeability challenging to carry out.
Creating model building blocks for epoxy/amine coatings is the first step in
carrying out these studies. We will demonstrate the synthesis and
characterization of model amine building blocks from saturated fatty acids and
simple amines such as diethylenetriamine (DETA) and Bis(3-aminopropyl)amine.
The structure-property relationship of thermosets made from these model
amines and Diglycidyl ether of bisphenol A (DGBEA) will be
discussed.
