- Title
HPLC Determination of Residual Primary Amine Content in Epoxy-Amine Adducts.

- Abstract
Epoxy-amine adducts are an amine blend added to hot-sprayed aromatic isocyanate-containing polyurea sprays to change the curing time. Polyurea sprays are applied to metallic surfaces to create an anti-corrosive coating and their curing time is influenced by the amine content. Amine content is normally determined using titration, but high performance liquid chromatography (HPLC) also has a high potential. Based on previous studies, HPLC with UV detection analysis could be performed for this purpose, if the samples are in their derivatized form. The goal of this study was to find an optimal derivatization method and to validate it to determine commercially available epoxy-amine adducts.
